Abstract
A new image encryption algorithm based on logistic map and hyper-chaos is proposed in this paper. The logistic chaotic sequences are modified to generate the chaotic key 1 which have a better randomness. A hyperchaos system is employed to produce the chaotic key 2. Encryption algorithm includes two rounds of image encryption based on double kinds of keys. The Ciphertext diffusion mechanism is produced in encryption process. The simulation results show that image encryption algorithm has a good results, high efficiency, good statistical characteristics and differential characteristics.
