The security of image information is becoming a growing concern, image encryption technology is becoming more and more comprehensive. The algorithm encrypts the image chunks, decoding and operation mode of each image block. It cannot resist clipping attacks, this paper increases the number of chaotic systems in the algorithm and optimizes the encryption process. The results show that the key capacity of the improved encryption algorithm is increased to 10127, which can resist the exhaustive key attack. After encryption, the correlation of adjacent elements of the image is reduced to 103 orders of magnitude, and The encrypted image is crop-resistant.
