Abstract

Some electronic data exchanged on internet are very critical and may be intercepted by malicious people for passive or active attacks; to protect these data, many cryptographic algorithms have been elaborated to ensure confidentiality and integrity. In this context we define and we implement a new secure and fast symmetric cryptographic scheme named Novel Encryption Scheme using Cellular Automata (NESCA) using irreversible cellular automata and a series of non-uniform cellular automata to generate cipher texts and to reconstruct plain texts. The process of encryption is applied on blocks of data and runs according to a number of rounds applying sub keys generated by cellular automata. To prove the reliability of the proposed system, a couple of tests are carried out and a comparison with AES-256 is presented.
