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?).

Advertising

Advertising as referred to in most economic books is part of the marketing mix. Therefore advertising usually is closely associated with the aim of selling products and services. Still, developments like "branding" show a tendency towards the marketing of not only products and services, but of ideas and values. While advertising activities are also pursued by political parties, politicians and governmental as well as non-governmental organizations, most of the money flowing into the advertising industry comes from corporations. Although these clients come from such diverse fields, their intentions hardly differ. Attempting to influence the public, their main goal is to sell: Products, services, ideas, values and (political) ideology.

Governmental Regulations

The new U.S. regulations are based on the Wassenaar Arrangement Revision of 1998, where exports without license of 56 bit DES and similar products are allowed after a technical review, just like encryption commodities and software with key lengths of 64-bits or less which meet the mass market requirements.
For more information see:
http://www.wassenaar.org/

Seven states stay excluded from the new freedom. These are states like Libya, Iraq, Iran, North Korea and Cuba, altogether states seen as terrorist supporting. No encryption tools may be exported into those countries.

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.

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. (...) Just because you can retire before it all blows up doesn't make it any less irresponsible."
(Arnold G. Reinhold)


The Chinese State Encryption Management Commission (SEMC) announced in March 2000 that only strong encryption tools will have to be registered in the future. Which sounds so nice on first sight, does not mean a lot in reality: any kind of useful encryption technique, like the PGP, stay under governmental control.

The restrictions and prohibitions for cryptography are part of the states' wish to acquire more control - in the name of the battle against criminality, probably?
Due to the emerging organized criminality the governments want to obtain more freedom of control over citizens. Organizations like the NSA appear as the leaders of such demands.
What about civil rights or Human Rights?

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.

Server

A server is program, not a computer, as it sometimes said, dedicated to store files, manage printers and network traffic, or process database queries.

Web sites, the nodes of the World Wide Web (WWW), e.g., are stored on servers.

ciphertext

the enciphered/encoded and primarily illegible text

Censorship of Online Content in China

During the Tian-an men massacre reports and photos transmitted by fax machines gave notice of what was happening only with a short delay. The Chinese government has learned his lesson well and "regulated" Internet access from the beginning. All Internet traffic to and out of China passes through a few gateways, a few entry-points, thus making censorship a relatively easy task. Screened out are web sites of organizations and media which express dissident viewpoints: Taiwan's Democratic Progress Party and Independence Party, The New York Times, CNN, and sites dealing with Tibetan independence and human rights issues.

Users are expected not to "harm" China's national interests and therefore have to apply for permission of Internet access; Web pages have to be approved before being published on the Net. For the development of measures to monitor and control Chinese content providers, China's state police has joined forces with the MIT.

For further information on Internet censorship, see Human Rights Watch, World Report 1999.

Hieroglyphs

Hieroglyphs are pictures, used for writing in ancient Egypt. First of all those pictures were used for the names of kings, later more and more signs were added, until a number of 750 pictures
