摘要
提出了一种基于混沌理论和循环移位的图像加密算法。先产生一个混沌序列,然后利用该序列与原图像进行异或运算和循环移位,得到初步加密图像,最后对图像进行Arnold变换得到加密图像。测试结果表明,该算法具有加密效果好、速度快、密钥空间大等优点。
A kind of image encryption algorithm is presented based on chaos theory and cycle shift. Firstly a chaos sequence is generated, then the pre-encrypted image based on XOR operation and cycle shift is obtained, and encrypted image is achieved by Arnold mapping on the pre-encrypted image, The experimental results show that this method has the advantages of good encryption effect, fast encrypting and large key space.
