一种信息系统用户密码的生成方法

摘要

Some disadvantages for user password generation method of the common information system and how to solve these drawbacks so as to increase the security of the information system were pointed out .By improvement of SHA2 the problems above mentioned can be solved .The ideas through introducing encryption key and multiple algorithm combination to realize automatic passwords assigned were put forward which can provide password text in flexible way .%指出了常见的信息系统用户密码生成方法存在的一些弊病以及如何解决这些弊病，从而提高信息系统的安全性。通过对SHA2的改进来解决上述问题，提出了引入密钥及多重算法组合来实现自动密码分配的思路，并可以灵活的方式提供密码文本。
