Liao Xuefen · Journal of Wenzhou University · 2014
An analysis is made on an image encryption algorithm based on chaotic Logistic system and dual transformation,and a method to decode the cipher-image based on chosen plaintext attack is found out.An improved algorithm based on chaotic Logistic system and dual transformation is proposed.Simulation experiments and security analysis are performed.The theoretical analysis and experimental results show that the improved algorithm can resist chosen plaintext attack,and has better cryptographic performances in many other aspects.
