A Tool for Privacy The algorithm being the code leads to encryption. When Alan Turing worked on his Turing Machine, he planned a machine where the instruction-code was part of its working, where the binary code was a fixed logic in dispute, in other words the machine turning into its own algorithm, which means nothing else than dialectic. And exactly here the theoretical work on cryptography touches - as a consequence of the actor always having been part of the technical arrangements - an issue of modern democracy, the question about the private and the public: the terms are changing, do not fit to their original meanings anymore. One might say the Internet is something private. One might state the contrary. Both sentences are wrong. It is neither of them. Maybe we do not all feel it yet, but humans are going through a stage of blurred words, where classic definitions get lost, just like the codes/algorithms of behavior. The meta-narratives break down, not leaving anything but puzzle pieces. We can never be private on the Internet. Nor could we be in public if we were "out there" in virtual reality. Cryptography, the study pretending to work for privacy, cannot provide us with absolute privacy either, as the danger of losing it through a decryption attack hinders its prospering. At the latest with the quantum computers coming into existence the patterns of the encoded picture will not be visible anymore. At the same time the social relations, its exact and excluding meanings must blur. Democracy needs something to rely on, something to refer to, just like the private and the public. Still, our need for privacy on the one hand and curiosity on the other hand create the longing for cryptography of information as well as its decoding. "Privacy is necessary for an open society in the electronic age. Privacy is not secrecy. A private matter is something one doesn't want the whole world to know, but a secret matter is something one doesn't want anybody to know. Privacy is the power to selectively reveal oneself to the world." (Cypherpunk's Manifesto) |

Cryptography's Terms and background "All nature is merely a cipher and a secret writing." Blaise de Vigenère In the (dis-)information age getting information but at the same time excluding others from it is part of a power-game (keeping the other uneducated). The reason for it eventually has found an argument called security. Compared to the frequency of its presence in articles, the news and political speeches security seems to be one of the most popular words of the 90's. It must be a long time ago when that word was only used for and by the military and the police. Today one can find it as part of every political issue. Even development assistance and nutrition programs consider it part of its work. The so-called but also real need for information security is widespread and concerning everybody, whether someone uses information technology or not. In any case information about individuals is moving globally; mostly sensitive information like about bank records, insurance and medical data, credit card transactions, and much much more. Any kind of personal or business communication, including telephone conversations, fax messages, and of course e-mail is concerned. Not to forget further financial transactions and business information. Almost every aspect of modern life is affected. We want to communicate with everybody - but do not want anybody to know. Whereas the market already depends on the electronic flow of information and the digital tools get faster and more sophisticated all the time, the rise of privacy and security concerns have to be stated as well. With the increase of digital communication its vulnerability is increasing just as fast. And there exist two (or three) elements competing and giving the term digital security a rather drastic bitter taste: this is on the one hand the growing possibility for criminals to use modern technology not only to hide their source and work secretly but also to manipulate financial and other transfers. On the other hand there are the governments of many states telling the population that they need access to any kind of data to keep control against those criminals. And finally there are those people, living between enlightening security gaps and at the same time harming other private people's actions with their work: computer hackers. While the potential of global information is regarded as endless, it is those elements that reduce it. There is no definite solution, but at least some tools have been developed to improve the situation: cryptography, the freedom to encode those data that one does not want to be known by everybody, and give a possibility to decode them to those who shall know the data. During the last 80 years cryptography has changed from a mere political into a private, economic but still political tool: at the same time it was necessary to improve the tools, eventually based on mathematics. Hence generally cryptography is regarded as something very complicated. And in many ways this is true as the modern ways of enciphering are all about mathematics. "Crypto is not mathematics, but crypto can be highly mathematical, crypto can use mathematics, but good crypto can be done without a great reliance on complex mathematics." (W.T. Shaw) For an introduction into cryptography and the mathematical tasks see: |

Napoleon Napoleon I. (1769-1821) was French King from 1804-1815. He is regarded as the master of propaganda and disinformation of his time. Not only did he play his game with his own people but also with all European nations. And it worked as long as he managed to keep up his propaganda and the image of the winner. Part of his already nearly commercial ads was that his name's "N" was painted everywhere. Napoleon understood the fact that people believe what they want to believe - and he gave them images and stories to believe. He was extraordinary good in black propaganda. Censorship was an element of his politics, accompanied by a tremendous amount of positive images about himself. But his enemies - like the British - used him as a negative image, the reincarnation of the evil (a strategy still very popular in the Gulf-War and the Kosovo-War) (see |

Adolf Hitler Adolf Hitler (1889-1945) was the head of the NSdAP, the National Socialist Workers' Party. Originally coming from Austria, he started his political career in Germany. As the Reichskanzler of Germany he provoked World War II. His hatred against all non-Aryans and people thinking in a different way killed millions of human beings. Disinformation about his personality and an unbelievable machinery of propaganda made an entire people close its eyes to the most cruel crimes on human kind. |

Alan Turing b. June 23, 1912, London, England d. June 7, 1954, Wilmslow, Cheshire English mathematician and logician who pioneered in the field of computer theory and who contributed important logical analyses of computer processes. Many mathematicians in the first decades of the 20th century had attempted to eliminate all possible error from mathematics by establishing a formal, or purely algorithmic, procedure for establishing truth. The mathematician Kurt Gödel threw up an obstacle to this effort with his incompleteness theorem. Turing was motivated by Gödel's work to seek an algorithmic method of determining whether any given propositions were undecidable, with the ultimate goal of eliminating them from mathematics. Instead, he proved in his seminal paper "On Computable Numbers, with an Application to the Entscheidungsproblem [Decision Problem]" (1936) that there cannot exist any such universal method of determination and, hence, that mathematics will always contain undecidable propositions. During World War II he served with the Government Code and Cypher School, at Bletchley, Buckinghamshire, where he played a significant role in breaking the codes of the German " |
