Late 1960s - Early 1970s: Third Generation Computers One of the most important advances in the development of computer hardware in the late 1960s and early 1970s was the invention of the Another type of computer developed at the time was the minicomputer. It profited from the progresses in microelectronics and was considerably smaller than the standard mainframe, but, for instance, powerful enough to control the instruments of an entire scientific laboratory.

Economic structure; digital euphoria The dream of a conflict-free capitalism appeals to a diverse audience. No politician can win elections without eulogising the benefits of the information society and promising universal wealth through informatisation. "Europe must not lose track and should be able to make the step into the new knowledge and information society in the 21st century", said Tony Blair. The US government has declared the construction of a fast information infrastructure network the centerpiece of its economic policies In Lisbon the EU heads of state agreed to accelerate the informatisation of the European economies The German Chancellor Schröder has requested the industry to create 20,000 new informatics jobs. The World Bank understands information as the principal tool for third world development Electronic classrooms and on-line learning schemes are seen as the ultimate advance in education by politicians and industry leaders alike. But in the informatised economies, traditional exploitative practices are obscured by the glamour of new technologies. And the nearly universal acceptance of the ICT message has prepared the ground for a revival of 19th century "adapt-or-perish" ideology. "There is nothing more relentlessly ideological than the apparently anti-ideological rhetoric of information technology" (Arthur and Marilouise Kroker, media theorists) | |||||||||||||||||||||||||||||||||||||

Key Recovery Systems As stated before the sense of cryptography is a properly designed cryptosystem making it essentially impossible to recover encrypted data without any knowledge of the used key. The issue of lost keys and the being-locked-out from one's own data as a consequence favors key recovery systems. On the other hand the counter argument is confidentiality: as soon as a possibility to recover a key is provided, the chances for abuses grow. Finally it is the state that does not want to provide too much secrecy. On the contrary. During the last 20 years endless discussions about the state's necessity and right to restrict private cryptography have taken place, as the governments rarely care for the benefit of private users if they believe in catching essential informations about any kind of enemy, hence looking for unrestricted access to all keys. The list of "key recovery," "key escrow," and "trusted third-party" as encryption requirements, suggested by governmental agencies, covers all the latest developments and inventions in digital technology. At the same time the NSA, one of the world's most advanced and most secret enterprises for cryptography, worked hard in getting laws through to forbid the private use of strong encryption in one way or the other. Still, it is also organizations like this one that have to admit that key recovery systems are not without any weaknesses, as the U.S. Escrowed Encryption Standard, the basis for the famous and controversially discussed Clipper Chip, showed. The reason for those weaknesses is the high complexity of those systems. Another aspect is that key recovery systems are more expensive and certainly much less secure than other systems. So, why should anyone use them? In that context, one has to understand the legal framework for the use of cryptography, a strict framework in fact, being in high contradiction to the globalised flow of communication. | |||||||||||||||||||||||||||||||||||||

History: "Indigenous Tradition" In preliterate societies the association of rhythmic or repetitively patterned utterances with supernatural knowledge endures well into historic times. Knowledge is passed from one generation to another. Similar as in the Southern tradition | |||||||||||||||||||||||||||||||||||||

Content as Transport Medium for Values and Ideologies With the dissemination of their content commercial media are among other things also able to transport values and ideologies. Usually their programming reflects society's dominant social, political, ethical, cultural and economical values. A critical view of the prevalent ideologies often is sacrificed so as not to offend the existing political elites and corporate powers, but rather satisfy shareholders and advertisers. With most of the worlds content produced by a few commercial media conglomerates, with the overwhelming majority of companies (in terms of revenue generation) concentrated in Europe, the U.S., Japan and Australia there is also a strong flow of content from the 'North-West' to the 'South-East'. Popular culture developed in the world's dominant commercial centers and Western values and ideologies are so disseminated into the most distant corners of the earth with far less coming back. | |||||||||||||||||||||||||||||||||||||

David Kahn David Kahn can be considered one of the most important historians on cryptography. His book The Codebreakers. The comprehensive history of secret Communication from Ancient Times to the Internet, written in 1996 is supposed to be the most important work on the history of cryptography. | |||||||||||||||||||||||||||||||||||||

1896 1896 The Daily Mail was published in Great Britain. It was the first newspaper for the masses. With the emerging of newspapers the manner how politics was perceived by the public changed completely. It became more difficult to keep secrets, while at the same time there was suddenly a new and nearly perfect tool for manipulation. | |||||||||||||||||||||||||||||||||||||

COMECON The Council for Mutual Economic Aid (COMECON) was set up in 1949 consisting of six East European countries: Bulgaria, Czechoslovakia, Hungary, Poland, Romania, and the USSR, followed later by the German Democratic Republic (1950), Mongolia (1962), Cuba (1972), and Vietnam (1978). Its aim was, to develop the member countries' economies on a complementary basis for the purpose of achieving self-sufficiency. In 1991, Comecon was replaced by the Organization for International Economic Cooperation. | |||||||||||||||||||||||||||||||||||||

Harold. D. Lasswell Harold. D. Lasswell (* 1902) studied at the London School of Economics. He then became a professor of social sciences at different Universities, like the University of Chicago, Columbia University, and Yale University. He also was a consultant for several governments. One of Lasswell's many famous works was Propaganda Technique in World War. In this he defines propaganda. He also discussed major objectives of propaganda, like to mobilize hatred against the enemy, to preserve the friendship of allies, to procure the co-operation of neutrals and to demoralize the enemy. | |||||||||||||||||||||||||||||||||||||
