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.

Convergence

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.

Censorship and Free Speech

There is no society - in the past or in the present - free of censorship, the enforced restriction of speech. It is not restricted to authoritarian regimes. Democratic societies too aim at the control of the publication and distribution of information in order to prevent unwanted expressions. In every society some expressions, ideas or opinions are feared. Censored are books, magazines, films and videos, and computer games, e.g.

In defence of its monopoly of truth, the Catholic Church published a blacklist of books not allowed to be read: the Index librorum prohibitorum. As indicated by the fact that every declaration of human rights - including the United Nations' Declaration of Human Rights and the European Convention on Human Rights - embraces free expression, democratic societies censorship is not imposed to protect a monopoly on truth or to foster the prevailing orthodoxy, as it seems. (With the remarkable exceptions of the prohibition of Nazi or Nazi-like publications and censorship practiced during wartime.) On the contrary, it is the point of free speech that we do not know the truth, that truth is something to strive for in a kind of public discourse or exchange intended to contribute to or even to constitute democracy. So "we cannot think coherently about free speech independently of issues about equality." (Susan Dwyer, A Plea to Ignore the Consequences of Free Speech, in: Computer-Mediated Communication Magazine, January 1, 1996, http://www.december.com/cmc/mag/1996/jan/dwyer.html) Racist expressions prove that. There are good reasons for supporting censorship to avoid violations of human dignity, as there are reasons to support unrestricted discussions of all topics.

To a high degree the Protestant Reformation was made possible by the invention of the printing press. Now those who were capable of writing and reading no longer needed to rely on the priests to know what is written in the Bible. They could compare the Bible with the sermons of the priests. This may be one of the reasons why especially in countries with a strong Protestant or otherwise anti-catholic tradition (with the exception of Germany), free speech is held in such high esteem.

There seems to be no alternative: free speech without restriction or censorship. But censorship is not the only kind of restriction of speech. Speech codes as politically correct speech are restrictions, sometimes similar to censorship; copyright, accessibility and affordability of means of communication are other ones. Because of such restrictions different to censorship, we cannot think coherently about free speech independently of issues about social justice. Many campaigns for free speech, the right of free expression are backed by the concept of free speech as unconstrained speech. That is perfectly well understood under the auspices of regimes prominently, which try to silence their critics and restrict access to their publications. But the concept of free speech should not solely focus on such constrains. Thinking of free speech as unconstrained speech, we tend to forget to take into account - to campaign against - these other restrictions. Additionally, free expression understood in that way offers no clue how to practice this freedom of expression and what free speech is good for.

In liberal democratic societies censorship is not justified by recurring to absolute truth. Its necessity is argued by referring to personal integrity. Some kind of expression might do harm to individuals, especially to children, by traumatize them or by disintegrating personal morality. Some published information, such as the names of rape victims, might infringe some people's right on privacy or some, as others say, such as pornographic images or literature, e.g., infringes some people's right on equality (how?).

Artificial Intelligence

Artificial Intelligence is concerned with the simulation of human thinking and emotions in information technology. AI develops "intelligent systems" capable, for example, of learning and logical deduction. AI systems are used for creatively handling large amounts of data (as in data mining), as well as in natural speech processing and image recognition. AI is also used as to support decision taking in highly complex environments.

Wide Application Protocol (WAP)

The WAP (Wireless Application Protocol) is a specification for a set of communication protocols to standardize the way that wireless devices, such as cellular telephones and radio transceivers, can be used for Internet access, including e-mail, the World Wide Web, newsgroups, and Internet Relay Chat (IRC).

While Internet access has been possible in the past, different manufacturers have used different technologies. In the future, devices and service systems that use WAP will be able to interoperate.

The European Convention on Human Rights and its Five Protocols

As can be read in the Convention's preamble, the member states of the Council of Europe, the European Convention on Human Rights is intended as a follow-up of the Universal Declaration of Human Rights proclaimed by the General Assembly of the United Nations on 10 December 1948 and as an official act of "securing the universal and effective recognition and observance of the Rights therein declared." Because it is stated "that the aim of the Council of Europe is the achievement of greater unity between its Members and that one of the methods by which the aim is to be pursued is the maintenance and further realization of Human Rights and Fundamental Freedoms", the European Convention on Human Rights can be read as the political sibling to the biblical Ten Commandments on which effective and legitimate European democratic government are based. The European Convention on Human Rights is intended to represent the essence of the common heritage of European political traditions and ideals.

Signed in Rome on November 4, 1950, the Convention is supplemented by five protocols dated from March 20, 1952 (Paris), May 6, 1963, September 16, 1963, and January 20, 1966 (Strasbourg).
