摘要 发送伪造路况消息的内部不端节点攻击是车载自组织网络(VANET)中的重要安全问题,而VANET中节点的隐私保护需求给解决这一问题带来难度。该文提出了一种在匿名VANET中隔离内部不端节点的协议,能够有效减小伪造路况消息给网络带来的威胁,在保护网络节点隐私的同时保证网络安全性。理论分析和仿真实验表明:该协议可以较低的代价,在匿名VANET中快速、准确地隔离内部不端节点,在这些节点被永久回收前为网络提供安全保障,并为权威机构最终回收这些节点收集证据。 One of the challenging security problems in vehicular ad hoc network（VANET） is preventing the misbehaving insiders from broadcasting bogus traffic status information.However,this problem becomes difficult to solve in anonymous VANET due to privacy-preserving mechanisms.This paper presents a protocol to efficiently isolate the misbehaving insiders from the anonymous VANET and mitigate the threats brought by the bogus messages,thus ensuring both the privacy and security in VANET.Analyses and simulations show that the protocol can achieve high reaction speed and accuracy in the local isolation against the misbehaving insiders at a low cost.The protocol is effective in protecting the whole network until these nodes are permanently revoked by the authorities,with evidences collected for the permanent revocation.
