摘要
陈刚等学者提出了一种新颖的自适应图像加密算法,周庆等学者分析表明该算法易受选择明文攻击和统计学攻击。为了提高该算法的安全性,本文提出了一种基于DES密码S盒的改进算法。分析表明,改进算法在安全性方面有更好的表现。
Chen etc. proposed a novel self-adaptive image encryption algorithm. The analysis by Zhou etc. shows that it is vulnerable to get selection plaintext attack and statistical attack. In order to improve its security,we proposed a revised algorithm based on the S-box of DES in this paper. The analysis shows that the revised algorithm has better performance on security.
