摘要/Abstract

摘要： 给出了对RIPEMD-128后三圈的碰撞攻击路线，理论上使其碰撞概率为2^-⁵⁵,低于生日攻击的2^-⁶⁴,的概率.

关键词: Hash 函数, 碰撞, 差分特征 , 差分分析

Abstract: The collision attack on the last three rounds of RIPEMD-128 is given. The probability of our attack can be found with 2^-⁵⁵, which is less than that of the birthday attack 2^-⁶⁴.

Key words: differential characteristics , differential analysis, collision, Hash function
