物联网中基于非线性对的漫游认证协议研究

物联网中移动传感结点的漫游认证对于物联网的应用十分重要，一方面移动传感结点的运算能力有限，另外一个方面对物联网的安全需求越来越高。在漫游过程中为了实现快速接入，同时确保其安全性，本文提出一种基于非线性对的漫游认证协议，该协议不仅具有轻量性，同时兼顾高安全性和实际可用性。本文从理论的角度分析了该协议即满足漫游协议的一般安全性，又满足漫游过程中不可跟踪性；从计算量的角度分析了该协议的运算量，通过对比发现该协议运算量较低；最后从模拟实验的角度分析该协议在复杂网络环境下的稳健性，从实验数据分析，该协议在中度恶劣环境下其稳健性较好。

A Roaming Authentication Protocol based on Non-linear

As the computation ability of mobile sensor nodes is limited, and there are higher and higher requirements put on the security of IOT, the roaming authentication of mobile sensor nodes is very important for the application of IOT. To realize fast access to IOT during roaming, and at the same time to ensure its security, we proposed a roaming authentication protocol based on non-linear pair in this paper. The proposed protocol is not only light-weighted, but also has high security and actual usability. First, we theoretically analyzed that the proposed protocol not only satisfies the generic security requirements of roaming protocols, but also satisfies the non-tracking performance during roaming. Secondly, we analyzed the computational amount of the proposed protocol, and found that the proposed protocol has low computational amount by comparison to other protocols. Finally, through simulated experiment, we analyzed the robustness of the protocol in complex network environment, and based on experimental data, we found that the protocol is quite robust under moderate severe environment.
