Startseite. Encryption. For as long as people have needed to conduct private conversations across distances, a variety of encryption methods have been used to protect secret communications.
However, the introduction of electronic communications networks raised an old encryption problem to a new level -- how do two people establish secure communications when they live so far apart that they can't meet first to exchange a secret decryption key? The solution to this problem is an encryption method called Public Key Cryptography (PKC), an ingenious mathematical structure that doesn't need participants to meet beforehand to conduct secure communications. PKC technology also provides a clever method of attaching an encrypted signature to a message to guarantee authenticity. PKC is now the engine for almost all high grade encryption on the Internet, including financial transactions on websites and implementation of the highest level virtual private networks.

Like the development of hypertext, packet switching is an idea that seems to want to have been discovered, found independently within a few years by two different people separated by one of the earth's largest oceans. The revolutionary concept formed the foundation for the design of the ARPANET, and then the Internet Protocol, providing the key enabling technology that has led to the success of the Internet today. The packet switching concept was a radical paradigm shift from the prevailing model of communications networks using dedicated, analog circuits primarily built for audio communications, and established a new model of discontinuous, digital systems that break messages into individual packets that are transmitted independently and then assembled back into the original message at the far end.
