An Image Fusion Encryption Algorithm Based on DNA Sequence and Multi-Chaotic Maps
In order to improve the security of image encryption algorithm, we presented a new image encryption algorithm. First, add two DNA sequence matrices produced by DNA encoding the original image and the key image. Then the added result of DNA sequence matrix is complemented by using Logistic chaotic map. At last, carry out decoding operation to the DNA sequence matrix which has been complemented, in this way we will obtain the encrypted image. The simulation experimental results and security analysis show that our algorithm can get good encryption effect, has widest secret key's space, strong sensitive to secret key, and has the ability of resisting exhaustive attack and statistic attack.
