"Bist du nicht willig, so brauch` ich Gewalt" -- ein Grundsatz, der mit moderner PC-Leistungsfähigkeit auch für einige Verschlüsselungsmethoden gilt. Im Zuge der immer weiter gehenden Vernetzung von Unternehmen, Haushalten und Privatpersonen wird ein gesicherter Datentransfer immer wichtiger. Auch wenn einige Institutionen gern suggerieren, guy befinde sich in einem hochgradig mafia-nahem Zustand, wünsche guy eine sichere Verschlüsselung für deepest electronic mail, zeigen politische Streitereien um weltweite Abkommen die Brisanz und Wichtigkeit starker Verschlüsselungstechniken.

It must be remarked however, that a sniffer is not only useful to villains like Mallory – it is also needed for legitimate test and control purposes. 3 network. One small comfort is that new forms of Ethernet reduce access to the medium of transmission. This works by the computers being linked to the network in star formation via a so-called hub or switch. In the hub, it is possible to filter data packets so that they only reach the correct receiver in readable form. This removes a large part of the danger of eavesdropping.

Or is it just a routine measure that takes very little effort? No matter what the reason, it can be taken as grounds for using cryptography. On this basis alone, the justification for the use of cryptography on the Internet cannot be denied, especially as on the Internet it is quite easy to analyse intercepted data, while snooping in the postal service needs a lot of personal effort. Data protection can so quickly become a farce. Also, there can be no disputing that secret services and investigative authorities also spy on private individuals on the Net – who knows how many strangers probably know everything about them, and whether that information has been gained in a legal manner or not?

If an eavesdropper should succeed, as described above, in gaining control of an exchange, then it is possible to divert any phone conversation. Interestingly, there are facilities called Witness and Monitor. These facilities are banned in many countries (in other countries they are permitted), although this doesn't mean that they are not available in Germany. Most manufacturers do not take the trouble to offer different versions of their equipment. Instead, they omit any mention of the forbidden facilities in their documentation.
