Correspondent Sensitive Encryption Standard (CSES) Algorithm in Insecure Communication Channel

Abstract

The purpose of the research was to implement the correspondent sensitive encryption algorithm for encryption of files and sending them through insecure communication channel. Currently, in practical applications correspondents are using either one known to them pair of keys (what has negative influence on security), use Public Key Infrastructure or as the simplest solution they are exchanging key through another channel. Additional benefits of our proposed solution are integrity control and ability to limit decryption capability to known recipients. The solution we propose allows correspondents to pair their devices fast and easily, so they could securely and without passwords transfer file through insecure channel.
