In recent years many chaos-based image cryptographic systems have been propos . In this paper a new color image encryption algorithm based on hyper chaos is proposed. The algorithm is composed of two parallel image encryption processes. In the first parallel process shuffled image pixels with two Logistic maps. Then image will be encrypted by Chen chaotic system. In the second parallel process, in the beginning magic square and logistic map are used for shuffling; after image is encrypted by Lorenz chaotic system. Finally, encrypted images from two parallel steps are combined to obtain the main encrypted image. Theoretical analysis and experimental results Theoretical that the proposed algorithm; includes the validity and security also it can with stand against brute-force attack
