A New Method for Image Encryption Using DNA Sequences and Hyper Chaos

In the decade of the significant progress in new communication sciences, digital images with a large amount of information are sent and received many times in different communication networks. Due to the high probability of manipulation and theft of some high-value digital images, as well as digital images that are of high value to the owner, they should be encrypted before transmission to be more secure. Several tools such as chaos functions, DNA coding, evolutionary algorithms, frequency domain transformations and substitution boxes have been used for image encryption. In this research, a new algorithm based on hyper chaotic map and DNA sequences is introduced to improve the security of the state-of-the-arts algorithms. The experimental analyzes show the efficiency of the proposed algorithm.
