物联网中基于非线性对的漫游认证协议研究

中文摘要: 针对当前移动传感节点的漫游认证协议在轻量性、切换速度和安全性等方面还存在缺陷，提出一种基于非线性对的漫游认证协议。在该协议方案中，从理论的角度分析该协议即满足漫游认证协议的一般安全性，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，与几种典型的移动节点的漫游认证协议相比，该协议在中度恶劣环境下其稳健性较好。
Abstract:In order to solve the problem that the roaming authentication protocol of current mobile sensing nodes has some defects in light weight property,switching speed,and security,a roaming authentication protocol based on non linear pair was put forward.Theoretical analysis showed that this protocol not only satisfies the general security requirements,but also the untraceability of current roaming authentication protocol.Computation and comparison showed that the protocol has a lower computation load.Finally,through simulation,the robustness of the protocol under complex network environment was analyzed.The comparison to the roaming authentication protocols of several typical mobile nodes showed that the present protocol processes good robustness under moderate severe conditions.
