| 摘 要： | 模差分分析是结合整数模减差分和XOR差分而定义的一种新的差分,与单一的模减差分或XOR差分相比,2种差分结合能表达更多的消息,从而可以更有效地分析、破解现有的哈希函数.MD5是哈希函数的一种,对消息的差分分析是对哈希函数实施碰撞攻击的重要手段,从目前已知的基于差分技术的攻击事实看,主要采用的是6比特差分和1比特差分.提...

| Abstract: | Differential cryptanalysis of module is a new differential which includes integer differential of module and XOR differential,and can express more messages in order to analyze and attack hash functions more effectively.MD5 is one of the hash functions.The strategy for determining message differential is the most important part of collision attacks against hash functions.So far,there have been two other message differentials attack published,one of which is 6-bit differential and another is 1-bit differentia... |
