As scientists are working hard on a quantum computer and also on quantum cryptography one can imagine that another revolution in the study of encryption has to be expected within the next years. By then today's hardware and software tools will look extraordinary dull. At the moment it is impossible to foresee the effects on cryptography and democratic developments by those means; the best and the worst can be expected at the same time. A certain ration of pessimism and prosecution mania are probably the right mixture of emotions about those tendencies, as the idea of big brother has come into existence long ago.
At the same time it will - in part - be a decision of the people to let science work against them or not. Acceleration of data-transmission calls for an acceleration of encryption-methods. And this again falls back on us, on an acceleration of daily life, blurring the private and the public for another time.
We live in an intersection, job and private life growing together. Cryptography cannot help us in that case. The privacy in our mind, the virtuality of all private and public lies in the field of democracy, or at least what is - by connection to the Human Rights - regarded as democracy.

Regarding the dimension of their financial and human resources commercial media companies are at any rate much more powerful players than their independent counterparts. Still those reply with an extreme multiplicity and diversity. Today thousands of newsgroups, mailing-list and e-zines covering a wide range of issues from the environment to politics, social and human rights, culture, art and democracy are run by alternative groups.
Moreover independent content provider have started to use digital media for communication, information and co-ordination long before they were discovered by corporate interest. They regularly use the Internet and other networks to further public discourse and put up civic resistance. And in many cases are very successful with their work, as initiatives like widerst@ndMUND's (AT) co-ordination of the critics of the participation of the Freedom Party in the Austrian government via mailing-lists, an online-magazine and discussion forums, show.

One of the most critical trends in the western culture what might be called the "fusion of flesh and machine". Increasingly, technological artifacts such as computers, rather than being used as tools by people, are functioning as parts of the human organism. On the other hand, human functionalities such as intelligence, emotion, adaptability or reproductivity are integrated into technological artifacts: the days when computers where only able to count apples and pears and their intelligence was not even matching an insect's are rapidly becoming history. Today, the boundaries between organisms and technology are losing their significance.
As new technologies are no longer mere instruments, or "extensions" of the organism, they acquire the capability of modifying the human organism - body and mind - from within according to certain pre-established principles. The history of the evolution of the human species is hastily being re-written as artificial beings begin to mock the categories of evolution and seem to work their way towards historical subjectivity. The German philosopher Günther Anders has extensively reflected on the changes of the human condition provoked by the development of modern technology speaks of an "antiquatedness of history" at a time when technology itself becomes a historical subject and men are becoming co-historical.
However, the softening of the biological definition of the human race is a theme which has accompanied western thinking ever since its origins. Beings half man-half animal crowd the tales of classical mythology and transcend the boundary between the human from below, while divine creatures, temporarily occupying humanoid bodies, relativise humanness form "above". What exactly "being human" meant and who "human beings" could be "defined" is a question with a long history. "Der Mensch ist das nicht festgestellte Thier" as Nietzsche commented.
Just as the boundaries between human and non-human are being crossed by technological development, so also the boundaries between the classical episteme are becoming permeable. Psychology is occupying itself with the emotions of machines, while physics and cybernetics is applied to the human mind and body. The "nicht festgestellte "character of humanness has meant that imagination has become just as relevant a factor in understanding humanness as science. Science fiction as a literary genre is no longer merely a depository of phantasies about a technisised world our of control. As the human monopoly on history seems to dissolve, the baroque narratives of science fiction have also become a resource for understanding history.
However, it is evident that the potentials of the new technologies gives rise not only to wild hopes and dreams and to bizarre stories; they also harbour some real ambiguities of a political and ethical nature. Not only does the merging of previously distinct realities - the human and the non-human worlds - unhinge theories and institutions based upon a clear distinction and separation of the two, it also is placing political practice on a different footing. Will artificial life have rights? Will artificial entities have political power? How will social relationships change?

The convergence of biology and technology is not an entirely new phenomenon but and has its origin in the concept of modern technology itself. This concept understands technology as something bigger, stronger, and more reliable than ourselves. But, unlike human beings, technologies are always tied to specific men-defined purposes. In so far as men define purposes and build the technology to achieve those purposes, technology is smaller than ourselves. The understanding of technology as a man-controlled tool has been called the instrumental and anthropological understanding of technology.
However, this understanding is becoming insufficient when technologies become fast and interdependent, i.e. when fast technologies form systems and global networks. Powerful modern technologies, especially in the field of informatics, have long ceased to be mere instruments and have created constraints for human action which act to predetermine activity and predefine purposes.
As a consequence, the metaphysical distinction between subject and object has become blurred. In the 1950s Heidegger already speaks of modern technology not as the negation but as the culmination of metaphysical thought which provokes men to "overcome" metaphysics. The weakening of metaphysical determinations which occurs in the project of modern technology has also meant that it become impossible to clearly define what being human is, and to determine the line that separates non-human from human being. These changes are not progressing at a controllable rate, but they are undergoing constant acceleration. The very efficiency and power of calculation of modern technologies means that acceleration itself is being accelerated. Every new technological development produces new shortcuts in socio-technical systems and in communication.

"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)
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.

According to a still widely held conviction, the global data networks constitute the long desired arena for uncensorable expression. This much is true: Because of the Net it has become increasingly difficult to sustain cultural and legal standards. Geographical proximity and territorial boundaries prove to be less relevant, when it does not affect a document's availability if it is stored on your desktop or on a host some thousand kilometers away. There is no international agreement on non-prohibited contents, so human rights organizations and nazi groups alike can bypass restrictions. No single authority or organization can impose its rules and standards on all others. This is why the Net is public space, a political arena where free expression is possible.
This freedom is conditioned by the design of the Net. But the Net's design is not a given, as
When the World Wide Web was introduced, soon small independent media and human rights organizations began to use this platform for drawing worldwide attention to their publications and causes. It seemed to be the dawning of a new era with authoritarian regimes and multinational media corporations on the looser side. But now the Net's design is changing according to their needs.
"In every context that it can, the entertaining industry is trying to force the Internet into its own business model: the perfect control of content. From music (fighting MP3) and film (fighting the portability of DVD) to television, the industry is resisting the Net's original design. It was about the free flow of content; Hollywood wants perfect control instead" (Lawrence Lessig,
In the United States, Hollywood and
For small independent media it will become very hard to be heard, especially for those offering streaming video and music. Increasingly faster data transmissions just apply to download capacities; upload capacities are much - on the average about eight times - lower than download capacities. As an AT&T executive said in response to criticism: "We haven't built a 56 billion dollar cable network to have the blood sucked from our veins" (
Consumers, not producers are preferred.
For corporations what remains to be done to control the Net is mainly to cope with the fact that because of the Net it has become increasingly difficult to sustain cultural and legal standards. On Nov 11, 1995 the German prosecuting attorney's office searched Compuserve Germany, the branch of an international Internet service provider, because the company was suspected of having offered access to child pornography. Consequently Compuserve blocked access to more than 200
Also in 1995, as an attack on US Vice-President Al Gore's intention to supply all public schools with Internet access, Republican Senator Charles Grassley warned of the lurking dangers for children on the Net. By referring to a Time magazine cover story by Philip Elmer-Dewitt from July 3 on pornography on the Net, he pointed out that 83,5% of all images online are pornographic. But Elmer-Dewitt was wrong. Obviously unaware of the difference between
Almost inevitably anxieties accompany the introduction of new technologies. In the 19th century it was said that traveling by train is bad for health. The debate produced by Time magazine's cover story and Senator Grassley's attack caused the impression that the Net has multiplied possible dangers for children. The global communication networks seem to be a inexhaustible source of mushrooming child pornography. Later would-be bomb recipes found on the Net added to already prevailing anxieties. As even in industrialized countries most people still have little or no first-hand experience with the Net, anxieties about child pornography or terrorist attacks can be stirred up and employed easily.
A similar and related debate is going on about the glorification of violence and erotic depictions in media. Pointing to a "toxic popular culture" shaped by media that "distort children's view of reality and even undermine their character growth", US right-wing social welfare organizations and think tanks call for strong media censorship. (See An Appeal to Hollywood,
The intentions for stimulating a debate on child pornography on the Net were manifold: Inter alia, it served the Republican Party to attack Democrat Al Gore's initiative to supply all public schools with Internet access; additionally, the big media corporations realized that because of the Net they might have to face new competitors and rushed to press for content regulation. Taking all these intentions together, we can say that this still ongoing debate constitutes the first and most well known attempt to impose content regulation on the Net. Consequently, at least in Western countries, governments and media corporations refer to child pornography for justifying legal requirement and the implementation of technologies for the surveillance and monitoring of individuals, the filtering, rating and blocking of content, and the prohibition of anonymous publishing on the Net.
In the name of "cleaning" the Net of child pornography, our basic rights are restricted. It is the insistence on unrestricted basic rights that needs to be justified, as it may seem.
Underlying the campaign to control the Net are several assumptions. Inter alia: The Net lacks control and needs to be made safe and secure; we may be exposed inadvertently to pornographic content; this content is harmful to children. Remarkably, racism seems to be not an issue.
The Net, especially the World Wide Web, is not like television (although it is to be feared this is what it might become like within the next years). Say, little Mary types "Barbie" in a search engine. Click
In reaction to these anxieties, but in absence of data how children use the Internet, the US government released the Communications Decency Act (CDA) in 1996. In consequence the
So, after the failing of the CDA the US government has shifted its responsibility to the industry by inviting corporations to taking on governmental tasks. Bearing in the mind the CompuServe case and its possible consequences, the industry welcomed this decision and was quick to call this newly assumed responsibility "self-regulation". Strictly speaking, "self-regulation" as meant by the industry does not amount to the regulation of the behaviour of corporations by themselves. On the opposite, "self-regulation" is to be understood as the regulation of users' behaviour by the rating, filtering and blocking of Internet content considered being inappropriate. The Internet industry tries to show that technical solutions are more favourable than legislation und wants to be sure, not being held responsible and liable for illegal, offensive or harmful content. A new CompuServe case and a new Communications Decency Act shall be averted.
In the Memorandum
In fact, the "self-regulation" of the Internet industry is privatized censorship performed by corporations and right-wing NGOs. Censorship has become a business. "Crucially, the lifting of restrictions on market competition hasn't advanced the cause of freedom of expression at all. On the contrary, the privatisation of cyberspace seems to be taking place alongside the introduction of heavy censorship." (
While trying to convince us that its technical solutions are appropriate alternatives to government regulation, the Internet industry cannot dispense of governmental backing to enforce the proposed measures. This adds to and enforces the censorship measures already undertaken by governments. We are encouraged to use today's information and communication technologies, while the flow of information is restricted.

No politician can win elections without eulogising the benefits of the information society and promising universal wealth through informatisation.

In the age of the vitreous man, whose data are not only collected by different institutions but kept under disclosure, out of reach, uncontrollable and unmanageable for the individual, privacy obtains new importance, receives a much higher value again.
The irony behind is that those who long for cryptography in order to preserve more privacy actually have to trust the same people who first created the methods to "produce" something like that vitreous man; of course not the same individual but persons of the same area of science.

Concerning their human and financial resources commercial media and independent content provider are an extremely unequal pair. While the 1998 revenues of the world's leading media conglomerates (AOL Time Warner, Disney, Bertelsmann, Viacom and the News Corporation) amounted to US$ 91,144,000,000 provider of independent content usually act on a non-profit basis and to a considerable extent depend on donations and contributions.

Agencies like the NSA are currently able to eavesdrop on anyone with few restrictions only - though other messages are spread by the NSA.
Theoretically cryptography can make that difficult. Hence those agencies speak up for actions like introducing trapdoors to make it possible to get access to everybody's data.
See the U.S. discussion about the Clipper Chip some years ago:
While encryption offers us privacy for the transmission of data, we do not only wish to have it but also need it if we want to transport data which shall not be seen by anyone else but the recipient of our message. Given this, the governments and governmental institutions/organizations fear to lose control. Strict laws are the consequence. The often repeated rumor that the Internet was a sphere of illegality has been proven wrong. Some parts are controlled by law very clearly. One of them is cryptography. Prohibition of cryptography or at least its restriction are considered an appropriate tool against criminality. Or one should say: had been considered that. In the meantime also governmental institutions have to admit that those restrictions most of all work against the population instead against illegal actors. Therefore laws have been changed in many states during the last five years. Even the USA, the Master of cryptography-restriction, liberated its laws in December 1999 to be more open-minded now.

This is, what happened in the USA, whereas in Germany the issue of a cryptography-law is still on the agenda. Until now, in Germany, everyone can decide by her-/himself, whether she/he wants to encrypt electronic messages or not. Some organizations fear that this could get changed soon. Therefore an urgent action was organized in February 2000 to demonstrate the government that people want the freedom to decide on their own. One governmental argument is that only very few people actually use cryptography. Therefore the urgent action is organized as a campaign for using it more frequently.
For more information on this see:
Other European countries have more liberate laws on cryptography, like France. Austria doesn't have any restrictions at all, probably because of a governmental lack of interest more than accepting freedom.
The (former) restrictions in the bigger countries influenced and hindered developments for safer key-systems, e.g. the key-length was held down extraordinarily.
"Due to the suspicious nature of crypto users I have a feeling DES will be with us forever, we will just keep adding keys and cycles (...). There is a parallel between designing electronic commerce infrastructure today that uses weak cryptography (i.e. 40 or 56 bit keys) and, say, designing air traffic control systems in the '60s using two digit year fields.

The company whose slogan is "Speed matters", is run by the Vietnam veteran Craig Ventor, whose declarations and business practices have given rise to widespread criticism. Unlike the Humane Genome Project, which is mapping the entire genome, Dr Ventor's method focuses on the genome information contained in messenger molecules. In keeping with Celera's slogan, this allows a much faster sequencing rate. The aggressive manoeuvring of Celera, coupled with Dr Ventor's unchecked self-esteem which lead him to compare himself to Nobel Prize winners, has meant that Dr. Ventor has been ostracised within the scientific community. James Watson, the co-discoverer of DNA, refers to Dr. Ventor's fast but relatively crude results as work that "any monkey could do" (source: BBC)

In this paper they are calling this orthodoxy the Californian Ideology in honor of the state where it originated. By naturalizing and giving a technological proof to a political philosophy, and therefore foreclosing on alternative futures, the Californian ideologues are able to assert that social and political debates about the future have now become meaningless and - horror of horrors - unfashionable. - This paper argues for an interactive future.

This book gives a fascinating glimpse of the many documented attempts throughout history to develop effective means for long distance communications. Large-scale communication networks are not a twentieth-century phenomenon. The oldest attempts date back to millennia before Christ and include ingenious uses of homing pigeons, mirrors, flags, torches, and beacons. The first true nationwide data networks, however, were being built almost two hundred years ago. At the turn of the 18th century, well before the electromagnetic telegraph was invented, many countries in Europe already had fully operational data communications systems with altogether close to one thousand network stations. The book shows how the so-called information revolution started in 1794, with the design and construction of the first true telegraph network in France, Chappe's fixed optical network.

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.

The water-clocks are an early long-distance-communication-system. Every communicating party had exactly the same jar, with a same-size-hole that was closed and the same amount of water in it. In the jar was a stick with different messages written on. When one party wanted to tell something to the other it made a fire-sign.

Expert systems are advanced computer programs that mimic the knowledge and reasoning capabilities of an expert in a particular discipline. Their creators strive to clone the expertise of one or several human specialists to develop a tool that can be used by the layman to solve difficult or ambiguous problems. Expert systems differ from conventional computer programs as they combine facts with rules that state relations between the facts to achieve a crude form of reasoning analogous to

Writing and calculating came into being at about the same time. The first pictographs carved into clay tablets are used for administrative purposes. As an instrument for the administrative bodies of early empires, who began to rely on the collection, storage, processing and transmission of data, the skill of writing was restricted to a few. Being more or less separated tasks, writing and calculating converge in today's computers.
Letters are invented so that we might be able to converse even with the absent, says Saint Augustine. The invention of writing made it possible to transmit and store information. No longer the ear predominates; face-to-face communication becomes more and more obsolete for administration and bureaucracy. Standardization and centralization become the constituents of high culture and vast empires as Sumer and China.

Communications satellites are relay stations for radio signals and provide reliable and distance-independent high-speed connections even at remote locations without high-bandwidth infrastructure.
On point-to-point transmission, the transmission method originally employed on, satellites face increasing competition from
In the future, satellites will become stronger, cheaper and their orbits will be lower; their services might become as common as satellite TV is today.
