A STATE-OF-THE-ART REVIEW ON PICTURE ENCRYPTION TECHNIQUES BY APPLYING LOGISTIC CHAOTIC MAP

Abstract

In this paper, we proposed a new algorithm for image encryption based on varied logistic chaotic map and dynamic algorithm parameters. The parameter-varied logistic map can cure logistic map vulnerabilities and resist the assault of phase space reconstruction. To shuffle the plain image, we use a parameter-varied logistic map and then use a dynamic algorithm to encrypt the picture. In order to evaluate its efficiency, we conduct numerous experiments, including histogram analysis, data entropy analysis, sensitivity analysis, key space analysis, correlation analysis and computational complexity. The results of the experiment show that this algorithm is highly secure and can be competitive with image encryption.
