Due to some features of images, traditional encryption algorithms are not suitable for practical image encryption. Considering this problem, a novel feistel network image encryption algorithm is proposed in this paper. Taking advantage of the desirable properties of mixing and sensitivity to initial parameters of chaotic maps, a sub key generator with couple chaotic maps is presented in this scheme. Meanwhile, the encryption algorithm includes a new mixing algorithm which is designed with thirty s-boxes of AES. To enhance the security of the new scheme, the encryption processes were combined in feistel network. The results of analysis and simulation experiments indicate that the scheme is secure and performed well in preventing attacks, such as brute force attack, entropy attack and statistics attack.
