Abstract: Orthomorphic permutations play important roles in the design of cryptosystem.Based on the equivalence of orthomorphic permutations and transversals of orthomorphic Latin square,some conclusions of orthomorphic permutations based on concatenation are obtained by researching the properties of linearity,fixed point,cycles and period.

Key words: orthomorphic permutation, orthomorphic Latin square, transversal, cycles, period

摘要: 正形置换在密码体制中有重要应用,根据正形置换和正形拉丁方截集的等价关系,研究了基于并置方法构造的正形置换的线性性、不动点、轮换和周期,给出了一些具体的结果。
