摘要: 车载网具有良好的发展前景,但同时存在严重的安全隐患,车载网安全认证方案是解决其安全性和可靠性问题的重要手段.以密码学相关知识为切入点,探讨了车载网安全认证方案合理设计的影响因素,并将其划分为内在因素和外在因素两大类;基于密码学的视角将车载网安全认证方案划分为2种类型:基于群签名和身份签名的安全认证方案和基于非双线性对的安全认证方案,阐述了2种类型各方案的特点和内容,按照安全特性、攻击地域范围和性能等方面进行了比较,以期为车载网的安全认证方案的设计和研究工作提供参考.

Abstract: VANET has a good prospect of development, but also it has the serious security risks at the same time. The security certification scheme of VANET is an important way to solve the security problem of VANET. This paper firstly takes the knowledge related to cryptography as the starting point and discusses the factors that influence the design of security certification schemes for VANET. Then based on the cryptography perspective, the paper classifies the security authentication scheme of VANET as two types: security authentication scheme based on group signature and identity signature and security authentication scheme based on non-bilinear pair. Lastly, it compares the characteristics of various schemes by the security characteristics, the geographical scope of the attack and the performance problems solved in order to provide reference for the design and research work of the safety certification scheme of the vehicle network.
