Timeline Cryptography - Introduction Besides oral conversations and written language many other ways of information-transport are known: like the bush telegraph, drums, smoke signals etc. Those methods are not cryptography, still they need en- and decoding, which means that the history of language, the history of communication and the history of cryptography are closely connected to each other The timeline gives an insight into the endless fight between enciphering and deciphering. The reasons for them can be found in public and private issues at the same time, though mostly connected to military maneuvers and/or political tasks. One of the most important researchers on Cryptography through the centuries is | ||||||||||||||||

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. | ||||||||||||||||

Transparent customers. Direct marketing online This process works even better on the Internet because of the latter's interactive nature. "The Internet is a dream to direct marketers", said Wil Lansing, CEO of the American retailer Many web sites also are equipped with One frequent way of obtaining such personal information of a user is by offering free web mail accounts offered by a great many companies, internet providers and web portals (e.g. However, the intention of collecting users personal data and create consumer profiles based on online behaviour can also take on more creative and playful forms. One such example is The particular way in which sites such as sixdegrees.com and others are structured mean that not only to users provide initial information about them, but also that this information is constantly updated and therefore becomes even more valuable. Consequently, many free online services or web mail providers cancel a user's account if it has not been uses for some time. There are also other online services which offer free services in return for personal information which is then used for marketing purposes, e.g. Yahoo's A further way of collecting consumer data that has recently become popular is by offering free PCs. Users are provided with a PC for free or for very little money, and in return commit themselves to using certain services rather than others (e.g. a particular internet provider), providing information about themselves, and agree to have their online behaviour monitored by the company providing the PC, so that accurate user profiles can be compiled.

Clipper Chip The Clipper Chip is a cryptographic device proposed by the U.S. government that purportedly intended to protect private communications while at the same time permitting government agents to obtain the "keys" upon presentation of what has been vaguely characterized as "legal authorization." The "keys" are held by two government "escrow agents" and would enable the government to access the encrypted private communication. While Clipper would be used to encrypt voice transmissions, a similar chip known as Capstone would be used to encrypt data. The underlying cryptographic algorithm, known as Skipjack, was developed by the National Security Agency (NSA). | ||||||||||||||||

WIPO The World Intellectual Property Organization is one of the specialized agencies of the United Nations (UN), which was designed to promote the worldwide protection of both industrial property (inventions, trademarks, and designs) and copyrighted materials (literary, musical, photographic, and other artistic works). It was established by a convention signed in Stockholm in 1967 and came into force in 1970. The aims of WIPO are threefold. Through international cooperation, WIPO promotes the protection of intellectual property. Secondly, the organization supervises administrative cooperation between the Paris, Berne, and other intellectual unions regarding agreements on trademarks, patents, and the protection of artistic and literary work and thirdly through its registration activities the WIPO provides direct services to applicants for, or owners of, industrial property rights. | ||||||||||||||||
