some essential definitions some essential definitions in the field of cryptography are: - cryptoanalysis - cryptology - ciphers "Few false ideas have more firmly gripped the minds of so many intelligent men than the one that, if they just tried, they could invent a cipher that no one could break." (David Kahn) codes plaintext ciphertext to encipher/encode to decipher/decode The variants of encryption systems are endless. For deciphering there exists always the same game of trial and error (first guessing the encryption method, then the code). A help to do so is pruning. Once, after a more or less long or short period a code/cipher breaks. Monoalphabetic ciphers can be broken easily and of course are no longer used today but for games. for further information on codes and ciphers etc. see: http://www.optonline.com/comptons/ceo/01004A.html http://www.ridex.co.uk/cryptology/#_Toc439908851

1980s: Artificial Intelligence (AI) - From Lab to Life Following the commercial success of expert systems, which started in the 1970s, also other AI technologies began to make their way into the marketplace. In 1986, U.S. sales of AI-related hardware and software rose to U.S.$ 425 million. Especially expert systems, because of their efficiency, were still in demand. Yet also other fields of AI turned out to be successful in the corporate world. Machine vision systems for example were used for the cameras and computers on assembly lines to perform quality control. By 1985 over a hundred companies offered machine vision systems in the U.S., and sales totaled U.S.$ 80 million. Although there was a breakdown in the market for AI-systems in 1986 - 1987, which led to a cut back in funding, the industry slowly recovered. New technologies were being invented in Japan. Fuzzy logic pioneered in the U.S. and also neural networks were being reconsidered for achieving artificial intelligence. The probably most important development of the 1980s was, that it showed that AI technology had real life uses. AI applications like voice and character recognition systems or steadying camcorders using fuzzy logic were not only made available to business and industry, but also to the average customer.

Radio Between the two World Wars the radio started becoming more and more important; as well in education (e.g. Walter Benjamin and Bertolt Brecht) as for propaganda. By hearing unconsciously, without listening, while concentrating on something else, it is easy to spread ideas and emotions. This fact was taken advantage of. The German Minister for Propaganda, Josef Goebbels, imagined the radio to be the most effective tool for propaganda. In fact the radio turned out to be a method to reach all generations at the same time, even the illiterates. By sending propaganda music and interrupting programs for the latest news, mostly good ones, the radio became popular. Radio Moscow, which started working in 1922, tried to intervene in innerstate-affairs in Britain as well as in other countries. The radio was supposed to push ahead the idea of communism.

Another voluntary Disinformation A very different form of voluntary disinformation are the calls for donations. Donations offer the possibility to do something good, to help the poor. Afterwards one does no longer have to feel guilty for being luckier than those "others". The same pictures of starving and desperate children for decades, of starving babies with big sad eyes. The pictures show a terrible life. But the idea that contributing money would change the destiny of those children and other people is a lie. States use their population for paying money to make the states' policy less unjust. In fact the money of the Western donators perpetuates the dependence and because of this prolongs the misery into a vicious circle of disinformation on both sides, but it is clever to have one's people believing that they can change the world.

The Right to get Disinformed Disinformation might also be welcome: While the ones criticize disinformation and try to fight against it, others do nothing against it. And others again seem to enjoy getting disinformed. How this works? It is the result of a society that does no longer want to live under the pressure of doing and hearing everything at the same time. Acceleration of life seems too fast. The only way to get out is to refuse certain things/messages/truths. Receiving disinformation can be more comfortable than getting so-called correct information. This is especially true for the readers of the yellow press. The yellow press lives on that perspective, the commodity of getting light news, mostly wrong news and lies - but those being wrapped up in nice pictures and stories about those who seem to reign the world. The aim is the escape out of reality. A surplus of information, information terror, can produce disinformation. The profusion can get exploited for disinformation. This works in that way that in the mass of information the individual has no possibility to get an overview of the different ways of thinking and to reach a stage of objective knowledge.

cryptoanalysis the study of breaking others' codes to transform a message back into a legible form without knowing the key from the beginning

INDEXCARD, 1/8

codes an algorithm for bringing a legible message into an illegible form. There has to exist some sort of code book to encode/decode it.

Division of labor The term refers to the separation of a work process into a number of tasks, with each task performed by a separate person or group of persons. It is most often applied to mass production systems, where it is one of the basic organizing principles of the assembly line. Breaking down work into simple, repetitive tasks eliminates unnecessary motion and limits the handling of tools and parts. The consequent reduction in production time and the ability to replace craftsmen with lower-paid, unskilled workers result in lower production costs and a less expensive final product. The Scottish economist Adam Smith saw in this splitting of tasks a key to economic progress by providing a cheaper and more efficient means of producing economic goods.

Moral rights Authors of copyrighted works (besides economic rights) enjoy moral rights on the basis of which they have the right to claim their authorship and require that their names be indicated on the copies of the work and in connection with other uses thereof. Moral rights are generally inalienable and remain with the creator even after he has transferred his economic rights, although the author may waive their exercise.

NSFNet Developed under the auspices of the National Science Foundation (NSF), NSFnet served as the successor of the ARPAnet as the main network linking universities and research facilities until 1995, when it was replaced it with a commercial backbone network. Being research networks, ARPAnet and NSFnet served as testing grounds for future networks.

Backbone Networks Backbone networks are central networks usually of very high bandwidth, that is, of very high transmitting capacity, connecting regional networks. The first backbone network was the NSFNet run by the National Science Federation of the United States.

cryptology also called "the study of code". It includes both, cryptography and cryptoanalysis
