Abstract Security in Vehicular Sensor Networks (VSNs) is a critical subject that must be addressed in the emerging Intelligent Transport Systems (ITS). Users share confidential information that can be used against them by attackers. Popular attacks include Malwares and Spams, Black Holes, Wormholes, and Physical/Electronic Outages. Such VSN attacks can lead to loss of life due to road accidents and breach of privacy. In this paper, we overview the VSN concept in a vehicular IoT-based smart city paradigm, focusing on the security aspects. In addition, we discuss the design features of VSN, its robustness, and reliability. We also discuss relevant communication technologies and their security concerns. We highlight the main open research issues in literature and provide hints for overcoming them. This analysis concludes that VSNs play a key role in developing efficient ITS. Nevertheless, current VSNs security standards must be improved for a reliable, and safe transportation system.

支持物联网 (IoT) 的智慧城市中的智能、安全和车辆传感器网络：概述

摘要 车载传感器网络 (VSN) 中的安全性是新兴智能交通系统 (ITS) 中必须解决的一个关键主题。用户共享可被攻击者用来对付他们的机密信息。流行的攻击包括恶意软件和垃圾邮件、黑洞、虫洞和物理/电子中断。此类 VSN 攻击可能会因交通事故和隐私泄露而导致人员伤亡。在本文中，我们概述了基于车载物联网的智慧城市范式中的 VSN 概念，重点关注安全方面。此外，我们还讨论了 VSN 的设计特点、鲁棒性和可靠性。我们还讨论了相关的通信技术及其安全问题。我们突出了文献中的主要开放研究问题，并提供了克服它们的提示。该分析得出的结论是，VSN 在开发高效的 ITS 方面发挥着关键作用。然而，当前的 VSN 安全标准必须改进，以建立一个可靠、安全的运输系统。
