Abstract

For the problem of lower safety performance in literature [1] , an improved chaotic map gray image encryption algorithm based on information entropy has been proposed.The algorithm includes three portions: first,chaotic mapping generates random matrices to diffuse plaintext image matrix ; Second, DNA encoding the addition and subtraction as well as complement arithmetic rule makes plain image matrix better confusion; Third, information entropy modulation parameters of chaotic systems to resist chosen plaintext attack. Based on [1], a combination of information entropy, while maintaining a good efficacy and safety, but also successfully solved the problem can resist the literature [2] attack methods.
