Four-dimensional hybrid chaos system and its application in creating a secure image transfer environment by cellular automata

One of the most important and practical researches which has been considered by researchers is creating secure environments for information exchanges. Due to their structures, chaos systems are efficient tools in the are of data transferring. In this research, using a mathematical structure such as composing and transferring, we improve classical chaotic systems by creating a four-dimensional system. Then we introduce a new encryption algorithm based on the chaos and cellular automata. The security of the proposed environment which is evaluated using different types of security tests shows the efficiency of the proposed algorithm.
