基于混沌映射和Hash函数的图像加密算法
An image encryption algorithm based on chaotic map and Hash function
摘要
Abstract
An image encryption algorithm based on chaotic map and Hash function is proposed to enhance the coupling of per-mutation and substitution and improve the ability to resist chosen plaintext attack in image encryption based on permutation substitution procedure.The permutation sequence involved in the substitution procedure is used to enhance the coupling of permutation and substitution and increase the difficulty of cracking.The corrected encryption key is combined with the di-gest of the encrypted image to ensure the various processes of different images.The theoretical analysis and experimental re-sults show that the proposed algorithm not only has good encryption results,but also can resist chosen plaintext attack.关键词
