A new character encryption algorithm

Abstract

Secure communications involves the use of different cryptography methods [1]. A new, fast and secure character encryption algorithm (CEA) is proposed in this paper. CEA uses polynomial invertible functions defined on Galois Fields (GF) [2], with encryption keys as long as the message itself generated from chaotic signals [3]. Simulations are made and the performances of the CEA are analyzed based on the Matlab version of CEA.
