A Novel Encryption Scheme using Cellular Automata (NESCA)

15271

Many cryptosystems have been elaborated to ensure confidentiality and integrity of data exchanged on internet. In this context, we define and we implement a novel Encryption Scheme based Cellular Automata (NESCA). More precisely, this cryptosystem uses reversible and irreversible cellular automata to generate cipher texts and to reconstruct plain texts. The process of encryption runs on blocks according to a number of rounds applying in parallel a number of sub keys generated by cellular automata. To prove the reliability of the proposed system, an implementation is given with various tests as for instance diffusion and confusion associated to a comparison with AES-256 algorithm.
