Abstract :
Orthomorphism is a kind of elementary permutation with good cryptographic properties, which can be used for constructing the S-box in block cipher structure. This paper mainly discussed constructing some orthomorphisms with evolutionary computation, and got some orthomorphisms with high nonlinearity and low difference uniformity by evolutionary algorithm in the open documents for the first time.
