摘要 针对于车载自组织网络中的身份认证问题,提出一种新颖的基于身份的匿名认证方案,该方案在保护了车辆的身份隐私信息的同时不仅满足了车辆节点与路边单元节点间的身份认证的需求,而且确保了车辆节点之间的身份认证。该方案利用基于身份的密码技术,减少了系统管理公钥证书的工作量和对节点证书认证的代价。最后通过安全性和复杂性分析,结果表明该方案不仅易于实现,而且安全可靠并具有较低的计算复杂度及通信开销。 In this paper, it proposes an identity-based anonymous authentication scheme in VANET to preserve users’identity privacy. This scheme achieves the goals of mutual anonymous authentication not only between Road Side Unit(RSU)and On Board Unit(OBU), but also between OBU and OBU. The proposed scheme uses the technology of identitybased cryptography, such that the system does not need the load of managing public key certificates and further the units do not require the additional computations to verify the other’s certificate yet. Finally, it proves the security of the proposed scheme and analyzes its complexity. The analyzed results show that the proposed scheme is not only secure, but also easy to implement since it needs low costs in both computation and communication complexities.
