函数运算 meaning in English
functional operation
Examples
- The small range searching technique can correct 4 more conditions for the first iteration differential and 3 more conditions for the second iteration differential , thus improving the probability and the complexity to find collisions . the whole attack on the md5 can be accomplished within 5 hours using a pc with pentium4 1 . 70ghz cpu
关于hash函数的碰撞攻击最近几年取得了举世注目的成果，王小云等提出的基于模减的差分分析方法有效地攻破了md4 , md5 , ripmd , haval和sha - 0等一系列hash函数，其攻击算法复杂度都低于次压缩函数运算，在一般的个人电脑上运算都可以找到碰撞实例。
