She sees me as a procrastinator who is passionate about people and work. Communication Skills Test Report (Testyourself.psychtests.com, 2013) The report displays strengths, potential strengths, and limitations. As a C/S type personality, I tend to be passive in my approaches to people. According to Carbonell, ââ¬Å"you are one the most passive types, but you tend to be reserved in the ways others likeâ⬠(Carbonell, 2008, p. 77). This passive approach reveals my passion to help people on a personal level. (Uniquely You, 2013) Who is the ââ¬Å"Me I Seeâ⬠? The ââ¬Å"Me I Seeâ⬠has a C/S personality type. Passive by nature, I tend to give an impression of being disinterested in people or their issues. One of my motivating factors is being sure of otherââ¬â¢s expectations before proceeding (Axiomsoftware.com, 2013). I see me as a person who has solid strengths but noticeable weaknesses as well. I am precise when it comes to details and facts. However, if not presented with a question, I tend to withhold my opinions until asked. This speaks of my hesitancy to take any risks. I do tend to remain to myself and not be as outgoing as possible. Thinking more positively and not being afraid of failure can beneficial inà controlling my behavioral tendencies (Uniquely You, 2013) As I review my 360 Interview Survey Results from individuals that know me, both seem to express similar concerns. I am looked at as a person who procrastinates at times, taking time to feel out and get comfortable in situations. With these patterns, it is wise for me to come out of my comfort zone and be more decisive (Carbonell, 2008). I value support, stability, and accuracy. I rely on data before making decisions and more than likely, take an objective approach (Resources Unlimited, 2013). These attributes describe the ââ¬Å"rocking the boatâ⬠mentality. No one desires to be the person who rocks the boat or causes it to sink. My personality profile depicts this kind of mentality. According to Peterson, ââ¬Å"when flat-brained, we say crazy things that seem reasonable to us at the timeâ⬠(Petersen, 2007, p. 26). As a C/S Type Personality, my firm and strong personality can at times become damaging. One way to counter the flat-brain syndrome is to have goals that reduce emotional disturbance, clarify thinking, increase self-confidence, and build supportive friendships (Petersen, 2007). Thinking clearly can help me see different options and make decisive decisions. Hallmark Purpose I am committed to having the mindset Christ had toward His Father, seeking to glorify God in every area of my life. God did not intend for me to be passive and non-decisive in life. I am an overcomer and will conquer my fears. For whoever wants to save his life will lose it, but whoever loses his life for me will find it. (Matthew 16:25, King James Version). My desire in life is to work full time in ministry. I seek to serve God and others. My rationale for having the mindset of Christ is to simply reflect and embrace the true Christian lifestyle. ââ¬Å"Me I Want To Seeâ⬠. The person I want to see in me is transforming from a passive person to a purpose driven person. I do not desire to just simply get by in life in my relationships with others. Hesitancy is not productive. The courses in PAC500 are challenging me personally. Developing superior listening skills and solving the people puzzle is not just for my counselees. I am beginning to look at myself now before even considering anyoneââ¬â¢s problems. My purpose lies inà developing the whole man, inside and out. This first begins at home and spread abroad. My hallmark is now a solid foundation to build upon. I am currently looked upon as helpful and considerate. I have a servant mentality. The ââ¬Å"me I want to seeâ⬠, is adding the qualities of boldness and decisiveness in the continual process of developing the whole man. References Axiomsoftware.com. 1994.

Critique Of The Movie For Colored Girls English Literature Essay
Critique Of The Movie For Colored Girls English Literature Essay Problems that face women presented in the movie: All these women unknown to them cross paths and their lives interact throughout the movie. The movie is structured such that each of the women has their own stories and problems that are facing them. The movie is based on the problems that the women were facing at the period of the production of the play in 1975. Time has changed but the issues that were facing the women in the 1970s are still relevant in this day and age. This are still the same issues that women are facing in our current millennium. The movie slowly develops and all this women come together to openly share their troubles. The movie mainly revolves around the problems that the cast of nine African-American are facing in their lives. The issues presented in the movie mainly consist of HIV/STDS, rape, abortion, abandonment, infidelity and male cruelty. The paper is going to pick the theme of HIV and STDs, rape and infidelity and male dominance. HIV and STDs: The text has highlighted this as one of the major problem that faces women in the world. Many of them are infected by their unfaithful partner and are oblivious to the fact that they are infected until the symptoms of the infection start to show. The movie clearly has approached the issue of HIV and STDs in the society. The first character to present this theme is Kelly. Accompanied by her husband she visits a physician who after conducting a few tests tells her that she has an untreated sexually transmitted disease that she has had for a long time. The doctor explains to her n her husband that the untreated sexually transmitted infection has robbed her of her ability to have child bearing ability since her womb has become weakened. Kelly is distraught and run wait leaving her husband at the doctors office. Later that night at their home Kelly confesses to her husband what had really transpired so that she contracted the infection. She explains to him that long before the two were married she was having a sexual relationship with a man who unknown to her was having a sexual relationship with a friend of hers. She traces her infection to this incident in her life which she greatly regrets since it had caused her infertility. H er husband however is supportive and tells him that he loves her despite the incident. He decides to stand by her in her problems. This theme is also brought out by Jo who we see confronting her husband on his infidelity. Jo has recently discovered that her husband was having sexual relationships with other men. She had discovered this while the two were at an opera and Jo caught her husband exchanging glances with another man. She later had taken a HIV test which turned out to be positive. She discovers that her husband through his relationship had infected her with HIV and she asks him not to be sorry for anything since he knowingly committed the infidelity. She kicks him out of her house and she goes to share her problems with the other women in the movie. Juanita offers Jo comfort and readily offers her advice on how to live positively even with HIV. Juanita is on the forefront and advices women on the use of condoms so as to avoid unnecessary problems from sex. Rape: The text has discussed rape and has shown that in our present time the rate of rape is still high most of the rape cases go unnoticed and many women shy away from reporting such cases due to the stigma and shame that is attached to rape. Mainly in the developing world rape and sexual harassment is still a serious problem that faces women all around the world. The movie has effectively presented this plight. In the movie we see a number of rapes and sexual belittling of women which is a problem that is still face women in our current times. Yasmine in the movie is having what looks like a good time at a restaurant with a man named Bill at a restaurant. She later lets Bill into her house and he takes advantage of her. He undresses and undresses her. Her forces himself onto her, first he fiercely assaults her before raping her. Yasmine ends up in hospital and even with Kellys husband trying to ask her about the rape she offers no information but rather offers him a poem as her answer. We later learn in the movie that Billy had been stabbed by another woman who he had tried to rape also. The theme is advanced further in the movie in the scene where Alice is furious and bursts into Tangies apartment to confront her about her advising Nyla to go to the abortionists. In the ensuing argument it becomes apparent that Tangie is also a victim of rape. From the argument we learn that Tangies grandfather who was Alices father had raped her. It is also apparent that Tangies grandfather had had his way with Nyla. Alice also reveals that her father had raped her and taken her virginity at an early age. The scene also reveals that Alices father had forced her to have a baby with an old white man when she was just fifteen. The men that they had trusted the most and who were supposed to protect them had been the same people who had hurt them. Infidelity and male dominance: The movie also furthers this theme. This is shown first by the incident of Kelly contracting a sexually transmitted disease. She discloses to her husband that her previous lover was having a sexual relationship with her friend. It was this infidelity that had cost her the ability to bear children. Jos husband is always coming home late and when she confronted him at one point he claims that his phone battery had died. Jos husband had also infected her with HIV since he was having extra marital sexual relationships with other men. She confronts him about it and it becomes apparent that he was having unprotected sex with other men and thus had contracted HIV which he had passed on to his wife. Male dominance is also shown by Jos husband who claims that since Jo earns more than he does and provides for the family he feels that he has been robbed of his masculinity and has to succumb to her control. Crystals husband also exemplifies male dominance and sheer cruelty when he come home to find a man in the drive way. He quickly assumes that the man is his wifes lover and he storms into the house to confront her about it. He shouts and abuses her and eventually takes their children and he drops out of their apartment window. The children die from the fall. Jo then realizes the level of abuse that Crystal has to go through every day. Crystal had to suffer through this due to her husbands machismo that asserts to him that he had dominance over her since she was his wife and she was a woman. Bill also furthers the theme of male dominance since he forces himself on women so is Alices father who raped her and robbed her of her virginity. Male dominance in the movie has been built up on the lines of viewing women as sexual objects At the end of the movie all the women meet at the top of balcony and they all discuss openly their problems. They stand by each other and offer each other comfort through their struggles. They prove to the audience that women need to stick together and support each other through their problems.

A Woman Pouring Milk Essay -- Visual Arts Paintings Art
A Woman Pouring Milk In Ways of Seeing by John Berger, the way we have been taught to observe, learn and analyze art is criticized. Berger describes static images are an appearance that has been taken out of context, out of its original time and setting. He states that any image encompasses a way of seeing. The way we see a specific image is based on perspective. A piece of art can be interpreted in various ways; it is relative to every person. Throughout the text, Berger illustrates the different types of arts. Each one is a perfect example of the phrase ââ¬Å"Use your own interpretation.â⬠If looked at closely, one gets different ideas and understandings than others of the same image. Another way that paintings are interpreted or misinterpreted is through reproductions. Reproducing original pieces of art has been a large controversy as well, even a ââ¬Å"political issue,â⬠which is discussed by Berger. Berger places a painting by Vermeer in his book, but does not offer an explanation on the painting. He does this so we ask ourselves about the painting. The painting, ââ¬Å"A Woman Pouring Milkâ⬠, is a simple, self-explanatory image, yet simultaneously symbolizes much more. Most of Vermeerââ¬â¢s work involves women performing daily chores. In his stated painting, we see how the woman is focusing intently on pouring the milk. She does not look at the artist painting her, she does not look around the room as if bored, but staring at the task. The woman is using all her eff...

Human Culture and its Effects on Technology Essay -- Technology Techno
Human Culture and its Effects on Technology A fluid border exists between the influences of culture and technology on the environment. Culture is generally defined as the predominating modes of thinking and behaving that characterize the workings of a group, while technology is the collection of knowledge available to a society that aids it in crafting tools, practicing arts and skills, and extracting or accumulating materials. In some instances, a people's culture drives its pursuit of more highly advanced technologies, while in other cases the implementation of newfound technology alters and shapes culture. These relationships are clearly visible throughout the course of human history. This paper focuses on the effects of early human culture on the progress of technological advances. Some cultural developments with significant impacts on human technology that are especially of note are religion, warfare, and the value system of wealth. George Basalla writes that "necessity spurs on inventive effort" (6). Humans develop technology to meet their perceived needs, though need is a relative term. Technology may serve entirely different purposes within various groups of people, which indicates that it obtains its importance within a specific cultural framework (Basalla 12). Some cultures developed religion and brought it into their lives, which in turn yielded new technological innovation. Great intellectual leaps are also considered technology, and religion encouraged one of the most important: a system of writing. Writing is believed to have developed alongside religious practices, due to the necessity of timing rituals. This need brought the calendar into the world, as well as a new system of communication (Ehrlich 224). Writ... ...an culture has proven itself to be highly influential in the progress of technology. From key aspects of early culture, including religion, war, and concepts of wealth, have stemmed great technological achievements that have forever altered the culture of today.

Conduct Unbecoming by Barry England :: Conduct Unbecoming Military England Essays
Conduct Unbecoming by Barry England Conduct Unbecoming revolves around two important yet very different characters; Drake and Millington. They are both new to the army but have very different views of the regiment. When they first enter ââ¬Ëthe messââ¬â¢ Drake looks about ââ¬Ëas a man finally at peaceââ¬â¢ Whereas Millington looks with gloom. Drake starts ââ¬ËExactly as I imagined it would beââ¬â¢ whereas Millington launches straight into sarcasm with ââ¬Ëhow very uplifting for you.ââ¬â¢ He makes a point that the place ââ¬Ëhaunted his childhoodââ¬â¢, showing us that not only does he hate it but he has also been there before. We now know that he already has some connection with the regiment. When Drake says ââ¬Ëit is likeâ⬠¦coming homeââ¬â¢ Millington replies with ââ¬Ëisnââ¬â¢t it, though?ââ¬â¢ We then find out that Millingtonââ¬â¢s father was in fact the colonel of the regiment until 1881. Drake obviously is in awe of the regiment and couldnââ¬â¢t be happier that h eââ¬â¢s there. He tells Millington ââ¬ËYou will find only military honours here. These are past colonels and holders of the Victoria Cross. That is the regimental tradition.ââ¬â¢ This shows how dedicated he is (that heââ¬â¢s learnt all this.) He then comments in a rather snobby way ââ¬ËI think I should warn you Millington, that while I might, through force of circumstance, tolerate your imbecilities throughout our voyage together, you will find that they are not appreciated hereââ¬â¢. Millington then tells Drake ââ¬Å"I have no intention whatever of surviving my probationary period. There is a ship, the Doric castle, which sails for England in almost exactly three months to the day from now. I intend to be on her.â⬠Showing that not only does Millington dislike the place but he has already got a plan, how he is going to get out of the regiment. We discover when Millington comments to Pradah Singh (the waiter) ââ¬Å"I fancy I could do great service to a large whiskey and sodaâ⬠¦Ã¢â¬ showing that he likes his drink, Drake quickly remarks ââ¬Å"We may neither order nor accept drinks until we are properly introduced into the mess.â⬠Drake is showing Pradah Singh how responsible he is and that he has really studied the rules of the regiment. When at last the Junior Sub arrives he asks if they Drake and Millington would like a drink. Millington jumps in with ââ¬Å"â⬠¦Just anything. Iââ¬â¢m about to expire.â⬠(More evidence that he likes to drink regularly) but Drake saves him by sucking up to the Junior Sub, saying ââ¬Å"My companion is joking of course.

Historical experience leader was not trusted Essay
Terry finished from college as an engineer with excellent grades. He got jobs with several companies within the space of two years after graduation. He decided to change job because of harsh environment conditions of the location of the companies. After staying at home for three months, he got another job with a university as an IT assistant, in charge of networking and system repairs. He was enjoying himself in this company: a young university graduate with bright future. He was very dedicated to the discharge of duties. Because of dedication to duty, he was loved by all and sundry. He actually also had good human relationships. During his stay in the company, he had three major plans: settle down for a family with his girl-friend. He wanted to continue his education by bagging a postgraduate degree in Information and communication technology. He also had a business plan to accomplish that would be open the door for his self-employment and own his company. Because of these, he was ready to get as much experience as possible. He was poised to learn as mush as would come his way. And he did. However, he started developing problems with his Unit director who felt he was outshining him in the Unit. They argued on several occasions about they had to do on network problems affecting the University Internet access. At last, he got a sack letter. He left the company. He did not particularly see the sack as a major problem: it was an opportunity for him to actually work on his plans. So, he set forth. He drew up his business plan: got fund from the savings and investments he had made while gainfully employed, from friends and family members. He got a vantage position for his IT Company that provides information and services on Website designs, PC sales and repairs, Internet access and Computer training. He got started with a number of hardworking staff. He made them understand that since the business is new, they had to see themselves as part of a team that must work hard to see that customers are satisfied, their requirements met and services delivered effectively. These workers understood and dedicated their time and energy to the progress of the Company. They trusted his knowledge and managerial skills. They were also ready to make sacrifices for the Company. I got employed into the company as a Customer Service agent in charge of customer relations and keeping a journal of order delivery status. I noticed that Terry had a problem with his girlfriend and he had to break up. This affected his mood and outlook to work in the office. During this time, he lost his vigor and strength. We got talking about many things, including our personal lives. He was articulate and intelligent. But he could not keep to schedule nor meet appointments. A lot of customers and some members of staff complained on this. He promised to change. But he did not. Apart from this, he refused to pay salaries for the first two months. This was not surprise to us as we knew that the Company was getting up and we understood that a lot of money had to go into the running of a new company. After the third month, we met to discuss why salaries had not been paid. The Accounting unit reported that the Company could pay its workers. Against his will, they also told those present that some people have been selectively paid. This got the ââ¬Ëunpaidââ¬â¢ workers annoyed and seriously vexed. We demanded for an explanation form the Boss. He was ready, as usual to give excuse and sweet-tongued us into this same old story: the Company is just catching up, and soon, all will be well. He supported his point with facts and figures convincing those paid are on special contract. He also used the opportunity to chastise workers who had not been working, especially those he had proposed to and they refused his advances. It later dawned on us that the company leader was making advances to many female workers in the office; those who agreed got paid and those who did not were chastised for their disobedience and were also not paid salaries. I was disappointed to come to this conclusion. I was learning a lot on the job, so I did not want to leave. After five months of endurance, we were paid for three months. I make proposal to opt out of the company because the situation grew worse daily. I called him several times to advise him but he would tell me I was young and had limited experience. Complaints by staff intensified daily. He sacked some, and others opted out willingly . The Situation became embarrassing: virtually everybody in the company knew about the ordeal. After series of threats, all salaries were paid. By then, he had lost a lot of resourceful workers. I also left the Company but not without lessons: little disappointments add up to big distrust. Trust is a major tool that makes communication effective. Anyone that loses this all-important trait is building a castle on sand, it would not last. Itââ¬â¢s only a matter of time: it would fall. The company no longer exists. It has now been closed down. Terry had to get a paid job to pay his debts.

Breaking DES (Data Encryption Systems)
Data Encryption Standard (DES) is an algorithm for decrypting and encrypting unstipulated information in the United States administration standard. DES is derived from IBMââ¬â¢s Lucifer code and is depicted by the Federal Information Processing Standards (FIPS) 46, with its current modification being FIDS 46-3 (Conrad, 2007). DES is a mass code that takes a plaintext sequence as a key in and generates a code transcript wording of the same measurement lengthwise.The mass of the DES obstruct is 64 bits which is also the same for the input dimension even though the 8 bits of the key are for the recognition of faults making the efficient DES input amount 56 bits. Because of the progressions in the authority of dispensation in workstations there are weaknesses in the 56-bit key extent presently (Conrad, 2007). In the company of proper hardware, there is a best chance assault on methodical efforts to all the 72 quadrillion hence, there is a possibility of dissimilar inputs.Advanced Encr yption Standard (AES) developed into an innovative FIPS-standard encryption average in 2001, 26th November to replace DES. Statistics Encryption Algorithm explains the definite algorithm as contested to the average. In such circumstances, TDEA is a short form for Triple DES. At the same time, there is a description of Triple Data Encryption Algorithm Modes of Operation ANSI X9. 52-1998 (Clayton & Bond, 2002). History of DES DES was proposed in 1975 and approved in 1977 as a federal information processing standard. It was criticized by the people who felt that itââ¬â¢s 56 key lengths to be insecure.In spite of this, DES remained a strong encryption algorithm until mid 1990. In the year 1998 summer, the insecurity of DES was demonstrated when a $ 250,000 computer which was built by the electronic frontier foundation decrypted a DES-encoded message in 56 hours. This was improved in the 1999 to 2002 hours through a combination of 100,000 networked personal computers and the EFF machi ne. DES remains a de facto standard unless a substitute is found (Landau, 2000, p. 341). A certified DES is obtained from the National Institute of Standards and Technology (NIST).This Advanced Encryption Standard (AES) works in three key lengths: 128, 192, and 256 bits. The publication of DES indicated a new era in cryptography. The development in the community of public cryptographers was enhanced by having an algorithm availability of study that the national security agent certified to be secure (Landau, 2000, p. 341). The (DES) Data Encryption Standard A system that encrypts quickly but is essentially what is impossible to break is all what cryptographers have always wanted. Public key systems have captured the imagination of mathematicians because of their reliance on elementary number theory.Public key algorithms are used for establishing a key because they are too slow to be used for most data transmissions. Private key system does the encryption because they are typically fa ster than public key ones (Landau, 2000, p. 341). The data Encryption Standard (DES) workhorse uses private key algorithm besides relying on cryptographic design principles that predate public key. The RC4 in web browsers and the relatively insecure cable TV signal encryption are an exception to DES. DES is the most widely used public cryptosystem in the world. It is the cryptographic algorithm which is used by banks for electronic funds transfer.It is also used for the protection of civilian satellite communications. Still, a variant of DES is used for UNIX password protection. There are three operation of the DES which involves XOR, substitution and permutation. The DES is an interrelated block cipher and a cryptosystem on a block of symbols that sequentially repeats an internal function which is called a round. It encrypts data by the use of a primitive that operates on a block of symptoms of moderate size. Self invert ability is also essential to enable one of the objects to enc rypt and decrypt. When encrypting ordinary text, DES begins by grouping the text into 64 bit block.A number of operations are performed by the DES on each block (Landau, 2000, p. 343). The transformation of how the block is to be carried out is determined by a single key of 56 bits. DES iterates sixteen identical rounds of mixing; each round of DES uses a 48-bit sub key. The DES begins with an initial permutation P and ends with its inverse. The permutations are of minor cryptographic implications but forms part of the official algorithm. The selection of sub keys starts by splitting the 56-bit key into two 28-bit halves and rotating each half one or two bits; either one bit in rounds 1, 2, 9, and 16 or two bits otherwise.The two halves are put back together and then 48 particular bits are chosen and put in order (Landau, 2000, p. 343). Attacks of DES The selection of DES was followed by protests in which case some of the researchers appeared to object to the algorithm small key spa ce. Investors in the key public cryptography claimed that a DES encoded message could be broken in about a day by a $ 20 million machine made up of a million specially designed VLSI capable of searching one key per microsecond while working in parallel.The use of a meet in the middle attack to break a four round version of DES did not extend past seven rounds (Landau, 2000, p. 345). This is evidence that, for all these attacks none of them posed a serious threat to the DES. Other attacks on the DES were performed to poke harder to the innards of DES. This brought anomalies which led to the first attacks that were seen to be more theoretically better than exhaustive search. The attacks were against the block structure system and the need of all block-structured cryptosystems needed to be designed to be secure against differential and linear cryptanalysis.There is a strong attack to DES which is differential cryptanalysis. This is apparently known to the algorithms designers. In order to design a secure cryptosystems, there is a need for a mixture of well known principles, some theorems and the presence of some magic. Attacks on a cryptosystem fall into two categories which are passive attacks and active attacks. The passive attacks are the ones which adversely monitors the communication channel. They are usually easier to mount although they yield less. The active attacks have the adversary transmitting messages to obtain information (Landau, 2000, p.342). The aim of the attackers is to determine the plaintext from the cipher text which they capture. A more successful attack will determine the key and thus compromise a whole set of messages. By designing their algorithms, cryptographerââ¬â¢s help to resist attacks such as cipher text only attack whose adversary has access to the encrypted communications. The known plain text attack which has its adversary has some plain text and its corresponding cipher text. The third attack which can be avoided is the chos en text attack and its adversary chooses the plain text for encryption or decryption.The plain text chosen by the adversary depends on the cipher text received from the previous requests (Landau, 2000, p. 342). Observations about DES The simplicity found in the DES amounts to some fully desirable properties. To start with it is the complementation. To illustrate, allow X to denote the bitwise complement of X. If C is the DES encryption of the plaintext P with key K, then P is the DES encryption of P with key K. In some cases the complementation can simplify DES cryptanalysis by basically cutting the investigating space in half.These properties do not cause serious weakness in the algorithm. The set generated by the DES permutations do not form a group. The group may have at least 102499 elements. There is strength in the DES when it lacks a group structure. It appears to be double encryption where this is twice by two different keys, EK2 (EK1 (P) and is not stronger than single encr yption. The reason is that when meeting in the middle attacks for a given plaintext cipher text pair, an adversary will compute all 256 possible enciphering of the plaintext i. e.EKi (P), and indexes the same. The adversary will then compute all possible deciphering of the cipher text (Landau, 2000, p. 345). Models of DES There are four forms of DES, which are accepted by FIPS 81. They include (ECB) Electronic Codebook form, code mass sequence form (CFB), productivity reaction form (OFB) and system response (CFB). The forms are used to with both DES and Triple DES. Within each form, there are main dissimilarities which are based on the fault proliferation and obstruct vs. tributary codes (Conrad, 2007). Electronic Codebook (ECB) ModeIn this form of encryption, there is sovereign encryption into respective blocks of codes text. It is done by means of Feistel code which generates 16 sub-inputs derived from the symmetric input and also encrypts the plaintext using 16 surroundings of co nversion. Similarly, the development is used in the conversion of code text reverse into simple text with the dissimilarity that, 16 sub inputs are contributed in overturn arrangement. The result of repeated blocks of identical plaintext is the repeated blocks of cipher text which is capable of assisting in the vault investigation of the code wording.In Appendix 1 there is an illustration of the result (Conrad, 2007). The first picture of SANS symbol is the bitmap layout. The second picture is the encrypted logo of SANS bitmap via DES ECB form. The visibility of the model is due to the recurring of masses of the simple wording pixels in the bitmap which are encrypted into masses which are repeated and are of particular code pixels. In this form, faults do not proliferate due to the autonomous encryption of each obstruct. Cipher Block Chaining (CBC) ModeThe CBC form is an obstruct code which XORs every original obstruct of simple wording with the previous block of code wording. This indicates that repeated obstructs of simple wording do not give rise to repeated obstructs of code wording. CBC uses a vector of initialization which is an arbitrary original obstructs used to make sure that two simple wordings result in different code wordings. In figure 2 of the Appendix there is a clear illustration of the same SANS symbol bitmap data, encrypted with DES CBC form. There is no visibility of any prototype which is true for all DES forms apart from ECB.Therefore, in this mode, there is proliferation of faults as each prior stepââ¬â¢s encrypted output is XORed with the original obstructing of simple wording (Conrad, 2007). Cipher Feedback (CFB) Mode The Cipher Feedback Mode is a tributary code that encrypts simple wording by breaking into X (1-64) bits. This permits encryption of the level of byte or bits. This mode uses an arbitrary vector of initialization. The preceding elements of code wording are XORed with consequent components of code wording. Therefore, in this mode of CBC there is proliferation of faults (Conrad, 2007).Output Feedback (OFB) Mode Similar to CFB form, the productivity reaction form makes use of the vector of random initialization and also encrypts simple wording by shattering downward into a tributary by encrypting components of X (1-64) bits of simple wording. This form fluctuates from CFB form by generating a simulated-arbitrary tributary of productivity which is XORed with the plaintext during every step. Therefore, the productivity is fed back to the simple wording and because the output is XORed to the simple wording, faults there is no proliferation of mistakes (Conrad, 2007).Counter (CTR) Mode The oppose form is a tributary code similar to OFB form. The main disparity is the accumulation of contradict obstructs. The offset can be supplementary to an arbitrary importance that is used only once and then increased for each component of simple wording that is encrypted. The initial counter obstructs acts as a vecto r of initialization. Therefore, in each surrounding there is XORing of the offset obstructs with simple wording. Accumulation of offset obstructs permits disintegration of encryption into equivalent phases, improving presentation on a suitable hardware.There is no proliferation of mistakes (Clayton & Bond, 2002). (Table 1 in the Appendix summarizes the Data Encryption Standard). Triple DES (T DES) In anticipation of 2030, TDES can be used as FIPS encryption algorithm which is permitted in order to allow conversion to AES. There are three surroundings of DES which are used by TDES which have an input extent of 168 bits (56 * 3). There is a possibility of reduced effective key length of TDES to roughly 12 bits though beast might assaults against TDES re not realistic at present (Conrad, 2007).Architecture for Cryptanalysis All modern day practical ciphers both symmetrical and asymmetrical make use of security apparatus depending on their key length. In so doing, they provide a margin of security to cover from computational attacks with present computers. Depending on the level of security which is chosen for any software application, many ciphers are prone to attacks which unique machines having for instance a cost-performance ratio (Guneysu, 2006).Reconfigurable computing has been recognized as way of reducing costs while also acting as an alternative to a variety of applications which need the power of a custom hardware and the flexibility of software based design such as the case of rapid prototyping (Diffie & Hellman, 1977, pp. 74-84). What this means is that cryptanalysis of todayââ¬â¢s cryptographic algorithms need a lot of computation efforts. Such applications map by nature to hardware based design, which require repetitive mapping of the main block, and is easy to extend by putting in place additional chips as is needed.However, it should be noted that the mere presence of resources for computation is not the main problem. The main problem is availab ility of affordable massive computational resources. The non-recurring engineering costs have enabled hardware meant for special purpose cryptanalysis in virtually all practicable situations unreachable. This has been unreachable to either commercial or research institutions, which has only been taken by government agencies as feasible (Diffie & Hellman, 1977, pp. 74-84).The other alternative to distributed computing with loosely coupled processors finds its base on the idle circles of the large number of computers connected through the internet. This method has considerably been successful for some applications. However, the verified detection of extraterrestrial life is considerably still a problem more so for unviable problems with power of computing in a particular organization (Guneysu, 2006). In cryptanalysis some algorithms are very suitable for special-purpose hardware.One main example for this is the search for the data encryption standard (DES) (FIPS, 1977). What this mean s is that a brute- force attack is more than twice the magnitude faster when put in place on FPGAââ¬â¢s as opposed to in software on computers meant for general purposes at relatively the same costs (FIPS, 1977). That notwithstanding, for many crypto algorithms the advantages due to cost-performance of hardware meant for special purposes over those meant for ordinary purposes is not really as dramatic as is usually the case of DES, more so for public-key algorithms (Guneysu, 2006).Arising from the advent of low-cost FPGA families with much logic approaches recently, field programmable gate arrays offer a very interesting way for the thorough computational effort which cryptanalysis needs (Lesnsta & Verheul, 2001, pp. 255-293). Many algorithms dealing with the most important problems in cryptanalysis is capable of being put in place on FPGAs. Code breaking though, requires more additional efforts as opposed to just programming a single FPGA with a certain algorithm (Electronic Fro ntier Foundation, 1998).Owing to the enormous perspectives of cryptanalysis problems, many more resources as opposed to FPGA are needed. This implies that the main need is massively powerful parallel machinery suited to the requirements of targeted algorithms. Many problems are capable of being put in parallel and are perfectly suited for an architecture distributed. Conventional parallel architectures for computing can theoretically be used for applications of cryptanalysis (Guneysu, 2006). An optical Architecture to Break Ciphers The targeted DES brute force attack has several characteristics.To begin with, expensive computational operations which are put in parallel. Next, there is no need of communication between single parallel instances. The next characteristic is the fact that the general expense for communication is not high owing to the fact that the stage of computation strongly outweighs the data input and output stages. According to Blaze et al, (1996), communication is almost entirely used for results reporting as well as initialization. A central control instance with regards to communication is capable of being accomplished by a conventional low cost personal computer, connected simply by an interface.This would imply that there is no need for a high-speed communication interface. The fourth characteristic is the fact that a DES brute-force attack and its following implementation require little memory. The final consequence of the above is the fact that the available memory on present day low cost FPGAs is sufficient (Guneysu, 2006). What this implies is that by making use of low-cost FPGAs, it is possible to develop a cost effective dynamic architecture which is capable of being reprogrammed which would be able to accommodate all the targeted architectures (Blaze et al, 1996).Realization of COPACOBANA Drawing back, the Cost-Optimized Parallel Code Breaker (COPACOBANA) meeting the needs available comprise of several independent-low prized FPGAs, connected to a hosting PC by way of a standard interface such as a USB. Moreover, such a standard interface permits to extend a host-PC with more than one device of COPACOBANA. The initialization of FPGAs, the control as well as the process of results accumulation is carried out by the host. Critical computations are carried out by the FPGAs, which meet the actual cryptanalytical architecture (Schleiffer, 2006).Developing a system of the above speculations with FPGA boards which are commercially available is certainly possible but at a cost. Therefore it is important to put into considerations the design and layout among others in coming up with the above kind of system (Schleiffer, 2006). This would therefore mean that our cost-performance design meant for cost optimization is only capable of being achieved if all functionalities are restricted to those required for code breaking. Arty the same time, many designs choices should be based on components and interfaces which are readi ly available (Guneysu, 2006).Conclusion In conclusion, cryptanalysis of symmetric and asymmetric ciphers is extremely demanding in terms of computations. It would be fair to hold the belief that breaking codes with conventional PCs as well as super-computers is very much costly. Bit-sizes of keys should be chosen in a way that traditional methods of code breaking do not succeed (Rouvroy et al 2003, pp. 181-193). This would mean that the only way to go through ciphers is to develop special-purpose hardware purposely meant for suitable algorithms.In the final analysis, traditional parallel architecture in the end equally appears to be too complicated and therefore not cost saving in finding solutions to cryptanalytical problems. As earlier observed, many of these problems can easily be put in parallel implying that the algorithms which correspond to them are equally capable of being parameterized to lower communication costs (Guneysu, 2006). A hardware architecture which is cost effec tive (COPACOBANA) is the end product of the algorithmic requirements of the intended problems of cryptanalysis.This work represents not only the design but also the first prototype of an effective design which meets the demands of the request. In the final analysis, COPACOBANA would be able to accommodate as many as 120 FPGAs which are less costly. At the same time, it is possible to break data encryption standard (DES) within a period of nine days. This would require a hardware design comprising of reprogrammable logic which could be adopted to accommodate any task, even those not necessarily in line with code breaking (Rouvroy et al 2003, pp. 181-193).
