A Novel Image Cryptosystem with Multiple Chaotic Maps

A novel secure image cryptosystem based on multiple chaotic maps is presented. In the algorithm, some keys generated by plaintext, together with the given keys control the parameters of the multiple chaotic systems to generate chaotic sequences, which are used to scramble positions and substitute grey values of pixels of image. Simulation results and analysis show that the proposed cryptosystem has good encryption performance, and it can resist brute-force attack, differential attack, statistical attack, chosen-plaintext attack.
