摘要:

针对VANET的无线、移动、分散、动态和带宽限制等特点可能存在的安全问题,基于地理区域将VANET分为若干个子网,子网车辆节点间通过CA(certificate authority)认证机制进行通信,子网之间则通过建立CA推荐信任模型进行通信。通过安全性分析可知该方案能较好地满足VANET对安全性的要求。

关键词: VANET;地理区域;CA

Abstract:

There might be some potential security problem according to the features of Vehicle Ad hoc networks(VANET), including wireless, shift, scatter, developments and bandwidth limitations. The security analysis shows that the program proposed in this paper can better meet the security requirements of VANET. The advice is that the VANET is divided into several subnets based on geographic region, and the traffics in the same subnet communicate with each other through the CA (certificate authority) authentication mechanism while the communications among the subnets need the establishment of CA recommendation trust model.

Key words:  vehicle Ad hoc networks; geographic region; certificate authority
