SAFER++ is selected for further evaluation in NESSIE second phase. A technique which connects differential cryptanalysis and nonlinear cryptanalysis is used to attack 4,5 and 6 rounds of SAFER++.

• SAFER + +是进入NESSIE第 2轮评估的 7个分组算法之一 采用差分密码分析和非线性密码分析相结合的方法对 4轮、5轮和 6轮SAFER + +进行分析 ,结果表明 :6轮SAFER + +对这种攻击方法不免疫 ;
