A MULTI-LEVEL APPROACH OF ELLIPTIC CURVE CRYPTOSYSTEM FOR ENHANCED SECURITY OF AMAZIGH ALPHABET USING CELLULAR AUTOMATA

Securing data is a challenging issue in today’s era. Encryption is one of the popular methods to achieve secret communication between sender and receiver. Many different encryption techniques have been proposed to save the security of information. Encryption provides only one level of security during transmission over the channel. Hence there is a need for a stronger encryption which is very hard to break. So, to achieve better results and improve security, information has to pass through several levels of encryption. The aim of this paper would be to provide new approach of elliptic curve cryptosystem using Cellular Automata (CA). The fundamental idea behind this encryption technique is to enhance security using the concept of cellular automata. The results show that the proposed algorithm has a high security feature and it is efficient for encrypting Amazigh alphabet. Practical implementation proved that the proposed encryption algorithm is robust and provides high level of security as compared to existing algorithms.
