A Modified Chaos-Based Image Encryption Algorithm
Ming Xu · Journal of Software · 2015
A modified image encryption algorithm based on the Arnold-Chen chaos image encryption algorithm is presented.The original one can't resist chosen-plaintext attack and known-plaintext attack, but the modified algorithm can resist both attacks by simply increasing one key and N horizontal-shifts.The simulation experimental results and security analysis show that the new algorithm has higher security while the encryption speed is as fast as the original one.Moreover, our modified method is transplantable , it can be used to modify other schemes which are easily exposed to differential attack.
