A Symmetric Color Image Encryption Scheme Using Hyper-Chaotic System and DNA Sequence Operation

A symmetric color image encryption scheme by using hyper-chaotic system and DNA sequence operation is proposed in this paper, which employs a chaotic shuffling matrix to shuffle the positions of image pixels and then uses XOR algebraic operation to XOR the scrambled image and the key image. The experimental results on USC data base demonstrate that the proposed encryption algorithm has a low time complexity and has the advantages of large key space and high security. Thus, our algorithm not only has good encryption effect, but also has the ability of resisting exhaustive attack and statistical attack
