摘要

车载 Ad-Hoc 网络(VANET)利用车载无线通信技术大大提高了驾驶的安全性和舒适性。由于 VANET 具有开放性,因此应提供有条件的隐私保护认证协议,以抵御潜在的攻击。在 VANET 中,车辆间高效、安全的身份验证是一项重要要求,但现有的用于保护 VANET 安全的有条件隐私保护身份验证协议存在各种局限性。为了解决这些固有问题,我们提出了一种基于共享组会话密钥(SGSK)的有条件隐私保护认证协议,该协议集成了自修复密钥分配技术、区块链和 MTI/C0 协议。在我们的协议中,我们使用 SGSK 代替耗时的证书撤销列表(CRL)检查,并通过更新 SGSK 来撤销恶意车辆。域内和跨域的未撤销车辆共享 SGSK。因此,当恶意撤销车辆进入一个新域时,它就很难访问系统并发送虚假信息。此外,我们的协议不仅能通过减少双线性配对的运算次数来提高计算效率,还能在保持条件隐私保护的同时抵御各种攻击。我们在 Hyperledger Fabric 平台上实现了我们的协议。实验结果表明,我们的协议可以在一秒内撤销跨域场景中的 180 辆恶意车辆,并能轻松满足每秒验证 600 条消息的要求。此外,我们的综合性能评估表明,我们的协议在车辆撤销检查成本、计算开销和通信开销方面都优于其他方法。此外,为了证明我们协议的可行性和有效性,我们使用 SUMO 和 NS2 模拟了实际的 VANET 场景,并验证了我们协议的效率和性能。仿真结果证明了我们的协议在 VANET 中的实用性。

Shared group session key-based conditional privacy-preserving authentication protocol for VANETs

Vehicular Ad-Hoc Networks (VANETs) have significantly enhanced driving safety and comfort by leveraging vehicular wireless communication technology. Due to the open nature of VANETs, conditional privacy-preserving authentication protocol should be offered against potential attacks. Efficient and secure authentication among vehicles in VANETs are important requirements, but there are various limitations in the existing conditional privacy-preserving authentication protocols for securing VANETs. To cope with the inherent issues, we propose a conditional privacy-preserving authentication protocol based share group session key (SGSK) by integrating the self-healing key distribution technique, blockchain, and MTI/C0 protocol. In our protocol, we use SGSK instead of the time-consuming Certificate Revocation List (CRL) checking, and we revoke malicious vehicles by updating SGSK. It is shared among unrevoked vehicles within a domain and across-domain. As a result, when a malicious revoked vehicle enters a new domain, it is difficult for it to access the system and send false messages. Furthermore, our protocol can not only achieve computation efficiency by reducing the number of computing operations of bilinear pairing but also resist various attacks while keeping conditional privacy protection. We implement our protocol in the Hyperledger Fabric platform. The experimental results show that our protocol is available to revoke 180 malicious vehicles in across-domain scenarios within one second, and it can meet the requirement of verifying 600 messages per second easily. Moreover, our comprehensive performance evaluations demonstrates that our protocol outperforms other approaches in terms of vehicle revocation checking cost, computation overhead, and communication overhead. In addition, to show the feasibility and validity of our protocol, we use SUMO and NS2 to simulate the actual VANET scenario and validate the efficiency and performance of our protocol. Simulation results prove the practicability of our protocol for VANETs.

期刊介绍: Vehicular communications is a growing area of communications between vehicles and including roadside communication infrastructure. Advances in wireless communications are making possible sharing of information through real time communications between vehicles and infrastructure. This has led to applications to increase safety of vehicles and communication between passengers and the Internet. Standardization efforts on vehicular communication are also underway to make vehicular transportation safer, greener and easier. The aim of the journal is to publish high quality peer–reviewed papers in the area of vehicular communications. The scope encompasses all types of communications involving vehicles, including vehicle–to–vehicle and vehicle–to–infrastructure. The scope includes (but not limited to) the following topics related to vehicular communications: Vehicle to vehicle and vehicle to infrastructure communications Channel modelling, modulating and coding Congestion Control and scalability issues Protocol design, testing and verification Routing in vehicular networks Security issues and countermeasures Deployment and field testing Reducing energy consumption and enhancing safety of vehicles Wireless in–car networks Data collection and dissemination methods Mobility and handover issues Safety and driver assistance applications UAV Underwater communications Autonomous cooperative driving Social networks Internet of vehicles Standardization of protocols.
