Usage of asymmetric encryption algorithms to enhance the security of sensitive data in secure communication

Abstract

Communication security is one of many informatics parts which have huge progress. Sensitive data are increasingly used in communication and that's the reason why is security requirement more timely and important. The risk of obtaining data through an attack increases with enhancing the power of today's computers. Paper attention is mainly devoted to sender authentication based on using digital signature and asymmetric encryption via one-way hash function to calculate public and private keys.
