基于现有动态口令身份认证技术的分析与改进

Analysis and improvement based on current dynamic password authentications

身份认证对于保证信息只被合法授权用户获取和访问起着重要作用,因而建立强有力的身份认证机制成为信息安全的关键之一。以现有动态口令身份认证主流技术为参照,提出了一种动态口令同步认证方法,以实现动态口令安全性、有效性与同步程度、验证效率之间的最优化配置。

The identity authentication plays an important role in protecting the information from unauthorized access. Hence a strong identity authentication mechanism becomes a key to the information security. A method off the dynamic password authentication based on the leading dynamic password identification technology is designed and solves the problem of the optimization collocation among security, validity, in-phase grad and authentication efficiency of the dynamic password.
