摘要
在传统的混沌序列加密算法的基础上,该文提出了一种新的Rossler混沌映射加密算法。该算法将图像的象素值进行了二次加密,且密钥也是经过混沌序列加密的,具有高度复杂性和安全性。通过MATLAB仿真得到的结果证明了其良好的保密性能,与理论结论相符。
A new improved map Rossler chaotic encryption algorithm was proposed in this paper,which based on the traditional chaotic sequence encryption algorithm.The algorithm encrypts the pixel values twice,and its key is also encrypted through the chaotic sequence with a highly complexity and security.By MATLAB simulation results,it shows that the confidentiality of its good performance fits with the theoretical conclusions.
