| 摘 要： | 针对传统的基于混沌的数字图像加密算法存在的抗差分攻击性能较弱、对受损密文图像恢复效果较差的问题,设计出一种基于分组密码和交替迭代结构的数字图像加密算法。在每一轮加密中,采用不同的耦合映像格子来构造S盒,使得算法具有更好的安全性能。实验结果表明,该算法不仅具有较好的加密效果,而且对受损密文图像也能得到较好的恢复效果。

| Abstract: | Aimed at the problems that traditional digital image encryption algorithm based on chaos performs weak in anti-differential cryptanalysis and has poor effect on recovery of impaired encryption image,a digital image encryption algorithm based on block cipher and alternating iteration structure is designed,which adopts different CML to form S-box during each round of encryption,bringing better security performance to the algorithm.Experiment results show that the algorithm not only possesses well encryption effect,but also very useful for the recovery of impaired encryption image. |
