Abstract: Orthomorphic permutations have good characteristic in cryptosystems.In this paper,the properties of orthomorphic permutations are discussed and some results are obtained. These results are useful in constructing orthomorphic permutations.

Key words: orthomorphic permutation, differential uniform, balanced function, linear structure, block cipher
