基于否定选择的身份认证技术

Identity authentication based on negative selection algorithm

为了提高用户身份认证的有效性,给出了一个集成肯定认证机制和否定认证机制的双层认证模型。首先,基于人体免疫系统T细胞识别自体和非自体的原理,设计了基于否定选择的身份认证机制;接着研究了否定认证机制的关键技术;最后给出双层认证模型的实现细节及性能分析。仿真实验表明,该身份认证模型能够承受各种口令攻击,有效过滤非法用户的登录请求,具有较好的鲁棒性和可用性。

To improve the validity of user identity authentication mechanism, a two-double authentication model integrating positive authentication mechanism and negative authentication mechanism was given. Firstly, inspired from the principle of immune cell identifying self and non-self, an identity authentication mechanism based on negative selection was designed; Secondly, key technologies of negative authentication mechanism were researched, and implementation details of model were given in the end. Simulation tests show that the identity authentication model can stand with password attacks, filtrate out invalid login requests availably, and have advantages of good robustness and reliability.
