Abstract—With the application of image in internet, security of image became an important issue. The paper designs an image encryption algorithm. Firstly, it analyzes a symmetric image encryption scheme based on a new chaotic map. Analysis shows it isn’t enough safe. Because there are a lot of week keys and duplicate keys in encryption. The diffusion mechanism is too simple to resist plain-text attack. The paper uses two chaotic maps at the same time to solve the problems. The maps are completely different. It designs a method of key generation. Thus it has large key space and avoids the duplicate key. At the same time parts of the key are used as the parameters of classic logistic map. It solves the problem of weak key. Several simulation results show the effectiveness of the algorithm.
