摘　　要：随着信息技术的发展,口令作为现代人必不可少的一种身份证明,已被广泛地应用于多种业务。然而,现行的通用口令体系却存在着一些不可避免的缺憾。该文首先分析了Internet上的不安全因素,然后对信息加密策略和现行口令机制予以分析,在此基础上提出了一种基于时间的一次一密口令的实现模型,最后对此模型和现行口令机制进行比较。With information era's coming,password has been used in many operations as a kind of absolutely necessary figure character of modern people.In computer operation system and database system,it is the first line of defense to identify users by the password.Unfortunately,the password system being used wildly nowadays has some unavoidable bugs.This paper analyzes the insecure factors of Internet and the password system used currently.Then authors bring forward a time-based one-time-one-password model.The main idea of the model is using a encrypting function to calculate three variables,two of which are time-based,then taking the result as password.At last,this paper compares the model with the current password system.
