Analysis of the Diffusion Property of Image Encryption Algorithm in Block-and-Permutation Mode and Its Implementation

摘要

摘要: 该文研究了分组排列模式下图像加密的扩散性能，提出了最优扩散性与无碰撞排列两个概念。最优扩散性指以最少的加密轮数实现图像的全局扩散性。在分组排列模式下，当且仅当排列算法满足无碰撞要求时，图像加密算法具备最优扩散性。根据无碰撞排列的概念提出了四叉树排列算法，并证明该算法可满足最优扩散性的要求。

Abstract: The diffusion property of image encryption algorithms in block-and-permutation mode is investigated, where two new conceptions, the optimal diffusion and collision-free permutation are put forward. An image encryption algorithm in block-and-permutation mode fulfills the requirement of optimal diffusion when the global diffusion is achieved within the ideally least round, which is feasible if and only if the permutation is collision-free. Further more, a permutation algorithm based on quadtree structure is proposed, which is proved to fulfill the requirement of the optimal diffusein.
