Abstract :Chaotic cryptography is a new field that has seen a significant amount of research activity during the last 20 years. Despite the many proposals that use various methods in the design of encryption algorithms, there is a definite need for a mathematically rigorous cryptanalysis of these designs. In this study, we analyze the security weaknesses of the “N. Bigdeli, Y. Farid, K. Afshar, A robust hybrid method for image encryption based on Hopfield neural network, Computers and Electrical Engineering 38 insert ignore into journalissuearticles values(2012); 356–369”. By applying Çokal’s attack, we show that all the secret parameters can be revealed.
Keywords : Chaos based cryptography, cryptanalysis, chosen plaintext attack
