摘要
口令是广泛使用的身份认证手段。应用动态口令系统是一种提高信息系统口令安全切实有效的方法。文章介绍了动态口令系统的研究和应用现状。在此基础上提出了一种新的基于挑战/响应机制的动态口令系统。该系统并未引入额外的认证硬件设备,分析表明该认证系统适合普通的互联网应用。
Password is the most widely used in ID authentication.Developing dynamic password system is a practical method of improving password security of information system.This paper introduces the brief history of research and implementation of dynamic password.And then a new dynamic password system based on challenge/response mechanism is provided.The proposed authentication system is simple to implement and secure for common Internet appliance without additional hardware involved.
