Zhijuan Deng, Shaojun Zhong · International Journal of Digital Content Technology and its Applications · 2013
This article firstly introduces image encryption algorithm in the thesis of A New Kind of Digital Image Encryption Algorithm based on Chaotic Mapping (hereafter referred to as XZQ algorithm) published by Xiong Changzhen et al.; then it analyzes this algorithm and adds plaintext information in encryption process on the basis of keeping original security and increasing no key quantity, enabling it to resist chosen-plaintext attack. The experimental results show that the encryption/decryption algorithm suggested in this article can effectively realize encryption/decryption on data of digital image.
