摘要
鉴于散列函数的单向不可逆性,介绍了一种利用散列函数实现网络远程身份鉴别的方法。该方法不需要在服务主机中预存口令表,可以有效防止和及时发现数据被篡改,为网络环境中的访问控制提供了一种简单且安全有效的机制。
This paper introduces a method of authentication based on hash function to realize remote authentication on network, which makes use of the one-way characteristic of hash function. The method needn't prearrange a password table on the server. And it can prevent information being tampered without being detected. So the method provides a simple and safely way to realize access control on network.
