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.

Movies produced in Hollywood in 1918/19 were mainly anti-German. They had some influence but the bigger effect was reached in World War II-movies.
The first propaganda movie of World War II was British.
At that time all films had to pass censoring. Most beloved were entertaining movies with propaganda messages. The enemy was shown as a beast, an animal-like creature, a brutal person without soul and as an idiot. Whereas the own people were the heroes. That was the new form of atrocity.

In the late twenties, movies got more and more important, in the USSR, too, like

The secret behind all this is the conception that nothing bad could ever be referred to the own nation. All the bad words belong to the enemy, whereas the "we" is the good one, the one who never is the aggressor but always defender, the savior - not only for ones own sake but also for the others, even if they never asked for it, like the German population during World War I and II.
The spiritualization of such thinking leads to the point that it gets nearly impossible to believe that this could be un-true, a fake. To imagine injustice committed by the own nation gets more and more difficult, the longer the tactic of this kind of propaganda goes on. U.S.-Americans voluntarily believe in its politics, believing also the USA works as the police of the world, defending the morally good against those who just do not have reached the same level of civilization until today.
To keep up this image, the enemy must be portrayed ugly and bad, like in fairy-tales, black-and-white-pictures. Any connection between oneself and the enemy must be erased and made impossible. In the case of
All of this is no invention of several politicians. Huge think tanks and different governmental organizations are standing behind that. Part of their work is to hide their own work, or to deny it.

The skytale (pronunciation: ski-ta-le) was a Spartan tool for encryption. It consisted of a piece of wood and a leather-strip. Any communicating party needed exactly the same size wooden stick. The secret message was written on the leather-strip that was wound around the wood, unwound again and sent to the recipient by a messenger. The recipient would rewound the leather and by doing this enciphering the message.
Galileo Galilee (1564-1642), the Italian Mathematician and Physicist is called the father of Enlightenment. He proofed the laws of the free fall, improved the technique for the telescope and so on. Galilee is still famous for his fights against the Catholic Church. He published his writings in Italian instead of writing in Latin. Like this, everybody could understand him, which made him popular. As he did not stop talking about the world as a ball (the Heliocentric World System) instead of a disk, the Inquisition put him on trial twice and forbid him to go on working on his experiments.
Fiber-optic cable networks may become the dominant method for high-speed Internet connections. Since the first fiber-optic cable was laid across the Atlantic in 1988, the demand for faster Internet connections is growing, fuelled by the growing network traffic, partly due to increasing implementation of corporate networks spanning the globe and to the use of graphics-heavy contents on the
Fiber-optic cables have not much more in common with copper wires than the capacity to transmit information. As copper wires, they can be terrestrial and submarine connections, but they allow much higher transmission rates. Copper wires allow 32 telephone calls at the same time, but fiber-optic cable can carry 40,000 calls at the same time. A capacity,
