Abstract: Quick trickle permutation can change the position of data,and the probability of the distance of every element is equal.So quick trickle permutation has good cryptographic properties.In this paper,two new encryption algorithm based on quick trickle permutation are proposed.

Key words: quick trickle permutation, image encryption, periodicity

摘要: 全距置换可以打乱数据的位置,同时又能使元素间距离的所有可能性都出现。所以从换位角度看,全距置换具有良好的密码学性质。将全距置换引入到图像加密的领域,提出了两种利用全距置换对数字图像进行加密的算法。
