基于交叉分段和并行扩散的混沌图像加密算法
Chaotic Image Encryption Algorithm Based on Cross Subsection and Parallel Diffusion
摘要
Abstract
Combined with the Logistic chaotic system,a novel algorithm is proposed based on cross subsection and parallel diffusion.The algorithm divides the plaintext into two segments to reduce the correlation between adjacent pixels of the plaintext.Each cipher text forms two rounds of parallel diffusion,which improves the sensitivity of algorithm for plaintext and key.Moreover,the algorithm adopts dynam-ic key generation rules,which makes the keystreams closely related to the plaintext.Experimental results and security analysis show that the chaotic image encryption algorithm based on cross subsection and parallel diffusion has a large key space,uniform distribution of the statistical characteristics,high sensitivity of the encryption system,and low time complexity etc.关键词
