Attack with Known Image to CMC Chaotic Image Encryption Algorithm
Jiansheng Guo, Lei Zhang · 2010
To study the security with known image of a symmetric image encryption scheme, the attack algorithm of equivalent key is given. We give the known image attacks under different other conditions to obtain the equivalent key. The concrete step and complexity of the attack algorithm is given. So the symmetric image encryption scheme based on 3D chaotic cat maps is not secure.
