The general structure of SAFER block ciphers adopts SP-network.It's desig n has some original features.In this paper, the design technique of SAFER block cipher is analyzed.Along the process of improvement of it's designers, we give a description of and attack on their confusion layer, diffusion layer and key schedule algo rithm.In the end, some problems about SAFER design are proposed, and will be studied later.
Key words： block cipher; SAFER; confusion layer; diffusion layer; key schedule
