Implementation the Protection Method of Data Transmission in Network

This paper proposes to solve the problems of protection of information against unauthorized access by introducing a system that, based on the developed methods of information exchange, performs a completely isolated from clients transmission. It provides a high level of protection, reliability and cryptographic stability of data transmission indicators. The system provides client-side message encryption with one of the crypto-encryption algorithms. The encrypted client message and the key to decrypt it are transmitted to a predefined server. The transmission is then encrypted by another algorithm that is defined on the server according to the method of assigning the encryption algorithm.
