查询词典 stepwise enhancement

Along with the password attack method unceasing renewal, the computation ability unceasing enhancement as well as to the operating speed request, the tradition disperses row algorithm MD5, SHA has demonstrated their shortcoming and the insufficiency day by day, and thestructure of hash function is mostly based on block cipher algorithm DES, but the HASH function security is established above the grouping function security, because the DES operand is very big, the operating speed very slowly by and its itself some characteristics, therefore disperses a row function based on the DES algorithm to have potential unsecurity.

随着密码攻击手段的不断更新、计算能力的不断提高以及对运算速度的要求，传统的散列算法MD5，SHA已日益显示出它们的缺点和不足，并且过去hash函数的构造多是基于分组密码算法DES的，而hash函数的安全性是建立在分组函数的安全性之上的，由于DES运算量很大、运算速度很慢以及其本身的一些特性，因此基于DES算法的散列函数具有潜在的不安全性。
