一种基于动态口令的身份认证系统研究

A Study of Authentication System based on Dynamic Password

身份认证在信息安全中起着非常重要的作用,建立安全的身份认证机制成为终端安全的关键之一。作为一种新型的认证模式,动态口令比传统的静态口令更加安全、可靠。本文阐述了动态口令的原理及现有动态口令方案的缺点,设计了一种新型的身份认证系统,并对其有效性进行了分析。

Identity authentication plays a very important role in the system security, establishing a secure authentication mechanism becomes one of the keys in the terminal security. As a new mode of authentication, dynamic password is more secure and reliable than traditional static password. This paper describes the principle of dynamic password and disadvantages of the existing dynamic protocols, designs a new type of authentication system and analyzes the effectiveness of it.
