$XSL$ block ciphers are based on Shannon's principles of confusion and diffusion. Round functions of these ciphers consist of round key addition, a substitution and a linear transformation. In this paper, the combinatorial properties of the group generated by the linear transformation and all round keys XOR-addition are described.
