Aiming at the application of a class of image encryption algorithm based on chaotic system, a chaotic image encryption algorithm based on Kent mapping and AES (Advanced Encryption Standard) encryption algorithm is proposed.Firstly, an initial condition is defined and a parameter related to plaintext pixel value is extracted as a key.The chaotic sequence generated by Kent is used as the target key of the AES encryption algorithm.Then, the plaintext and the target key are XOR-processed Finally, the target key is substituted into the algorithm to perform several AES encryption algorithms to obtain the ciphertext.The experimental results show that the proposed algorithm can resist the differential attacks and analyze the statistical characteristics well, but also can effectively resist the plaintext attack and the encryption effect is better.
