Abstract: In this paper,a method of solving the information encryption problems by using the permatation groups is presented.The algorithms of encryption and decrytion with permutation groups are demonstrated,and the encryption key and decryption key are explained.Besides,the authors point out there may be some problems while using the permutation groups to solve information encryption problems.
