CRYPTOGRAPHIC ALGORITHMS

Abstract

Security computer systems is becoming increasingly important, as more and more users in more ways used more and more information in the computer world. In such a system there is a growing risk of unauthorized use of information, planting false information or destroying information. In computer systems information is transmitted various open and insecure communication paths. Access to these roads can not be physically protected so every hostile attacker can disrupt the security system. Therefore, protective communication mechanisms over insecure communication channel becoming the most important form of achieving security. Indeed the most effective protection of their message encryption. In this article I'm going to explain the basic concepts related to encryption algorithms that have been used and that are used to protect the privacy of the network computers.
