The most advanced and emerging component of an intelligent transportation system (ITS) is the vehicular ad hoc network (VANET). Vehicles communicate with nearby vehicles or road side units (RSUs) in order to provide safety or non-safety information. This information containing vehicle ID, current position, speed and vehicle status is shared periodically among nearby vehicles. VANET provides tremendous benefits to drivers, but due to its inherent characteristics, it is important to address security and privacy issues before it can be fully adopted. It is required to authenticate the vehicles participating in the network and held responsible in case any type of misbehavior is encountered in the network. Traditional centralized security solutions are not suitable in VANET because of high speed of vehicles, minimal communication resources and delay sensitive applications. Blockchain is a decentralized and distributed computing platform that makes it easier to record and manage resources without relying on a centralized trusted authority. Therefore, blockchain based solution is expedient in VANET scenario which provides transparency, tamper resistance and immutableness. This paper aims to envision a comprehensive review on applications of blockchain in VANET security. We first present the introduction of VANET security and blockchain. Then, we conduct a literature review on the existing security solutions using blockchain in VANET by considering the technical issues and research problems. At last, we highlight some future research issues by reviewing the characteristics of both blockchain and VANET.

使用区块链的车载 Ad Hoc 网络的安全性:全面审查

智能交通系统 (ITS) 中最先进和新兴的组件是车载自组织网络 (VANET)。车辆与附近的车辆或路边单元 (RSU) 通信,以提供安全或非安全信息。包含车辆 ID、当前位置、速度和车辆状态的信息会定期在附近的车辆之间共享。VANET 为驾驶员提供了巨大的好处,但由于其固有的特性,在完全采用之前解决安全和隐私问题非常重要。需要对参与网络的车辆进行身份验证,并在网络中遇到任何类型的不当行为时承担责任。传统的集中式安全解决方案因车辆速度快而不适用于 VANET,最小的通信资源和延迟敏感的应用程序。区块链是一个去中心化的分布式计算平台,它可以更轻松地记录和管理资源,而无需依赖中心化的可信权威。因此,基于区块链的解决方案在提供透明性、防篡改和不可变性的 VANET 场景中是权宜之计。本文旨在全面回顾区块链在 VANET 安全中的应用。我们首先介绍 VANET 安全性和区块链。然后,我们结合技术问题和研究问题,对 VANET 中使用区块链的现有安全解决方案进行了文献综述。最后,我们通过回顾区块链和 VANET 的特点来强调一些未来的研究问题。区块链是一个去中心化的分布式计算平台,它可以更轻松地记录和管理资源,而无需依赖中心化的可信权威。因此,基于区块链的解决方案在提供透明性、防篡改和不可变性的 VANET 场景中是权宜之计。本文旨在全面回顾区块链在 VANET 安全中的应用。我们首先介绍 VANET 安全性和区块链。然后,我们结合技术问题和研究问题,对 VANET 中使用区块链的现有安全解决方案进行了文献综述。最后,我们通过回顾区块链和 VANET 的特点来强调一些未来的研究问题。区块链是一个去中心化的分布式计算平台,它可以更轻松地记录和管理资源,而无需依赖中心化的可信权威。因此,基于区块链的解决方案在提供透明性、防篡改和不可变性的 VANET 场景中是权宜之计。本文旨在全面回顾区块链在 VANET 安全中的应用。我们首先介绍 VANET 安全性和区块链。然后,我们结合技术问题和研究问题,对 VANET 中使用区块链的现有安全解决方案进行了文献综述。最后,我们通过回顾区块链和 VANET 的特点来强调一些未来的研究问题。
