摘　　要：全距置换具有良好的密码学性质。该文首次提出了全距特征排列的概念,对全距特征排列的性质、计数进行了研究,并在此基础上讨论了全距置换与全距特征排列之间的映射关系、最后基于全距特征排列给出了全距置换的一种有效的构造方法,首先构造全距特征排列,再求出全距置换。Quick trickle permutation has good cryptographic properties. In this paper, the concept of quick trickle characteristic sequence is presented, the properties and count of quick trickle characteristic sequence are researched, the mapping relation between quick trickle characteristic sequence and quick trickle permutation is discussed. Finally, a effective construction of quick trickle permutation based on quick trickle characteristic sequence is given, by which quick trickle permutation can be figured out after constructing quick trickle characteristic sequence.

关 键 词：全距特征排列 全距特征映射 密码学 全距置换
