Cryptographic Protocol

Abstract

Theoretical research in number theory has a long tradition. Since many centuries the main goal of these investigations is a better understanding of the abstract theory. Numbers are basic not only mathematics, but more generally for all sciences, a deeper knowledge of their properties is fundamental for further progress. Remarkable achievements have been obtained. Among the unexpected features of the recent developments in technology are the connections between classical arithmetic and on the one hand, and new methods for reaching a better security of data transmission on the other. In this paper we illustrate the aspect of the subject by showing the modern cryptography and its types like public key cryptography and private key cryptography its properties.
