摘要:

身份认证是车辆接入车联网(IoV)的第一道防线。然而现有方案还不能满足 IoV 的高效认证需求,也不能实现快速的匿名追溯。鉴于此,提出了一种 IoV 中双向匿名可追溯组认证协议。该协议先将多个路侧单元(RSU)进行快速动态的分组,并对进入 RSU 组的车辆利用切比雪夫混沌映射的单向陷门性和半群特性进行接入认证,当车辆在组内的RSU之间切换时采用反向哈希链进行快速切换认证。另外,组内RSU可以对恶意车辆进行身份的匿名追溯,并利用区块链对其身份进行快速撤销,还可以对泄露真实身份的用户进行ID的自由变更。同时运用随机预言机模型证明了协议的语义安全性。最后,通过仿真验证了该方案具有良好的安全性和有效性。

Abstract:

Identity authentication is the first line of defense for vehicles to access IoV (Internet of vehicles).However, the existing schemes cannot meet the requirements of efficient authentication of IoV well, nor can they realize fast anonymous traceability.In view of this, a bidirectional anonymous traceability group authentication protocol was proposed in IoV.In this protocol, a number of RSU (road side unit) were grouped quickly and dynamically.And the vehicles entering the RSU group were authenticated with the one-way trap gating property and semi-group property of Chebyshev chaotic map.When the vehicle switched between the RSU within a group, the reverse hash chain was used for fast handover authentication.In addition, the RSU within a group can trace anonymously and revoke the identity of malicious vehicles quickly by using blockchain, and can also freely change the ID of users who reveal their real identity.At the same time, the semantic security of the proposed protocol is proved by using the random predictor model.Finally, simulation results show the proposed scheme has good security and effectiveness.

Key words: IoV, anonymous traceability, chaotic mapping, group authentication, reverse Hash chain, blockchain
