Abstract :
This Cellular Automata (CA) has been used in cryptography over the past decade for its advantages in generating pseudo-random sequence. In this paper, a novel encryption algorithm for image in our project is proposed, which is based on an improved two-dimensional CA approach. A weighted and p-interval two-dimensional CA approach forms a new evolutionary matrix including lots of optional parameters that results in a great quantity of security keys. According to simulation results, a large number of sequences are encrypted effectively and quickly by this method.
