Integration of sensing, communication, computing, and intelligence (ISCCI) represents a pivotal advancement in B5G and 6G technologies, offering transformative potential for the Internet of Vehicles (IoV). As IoV systems become increasingly integral to intelligent transportation and autonomous driving, these systems also face escalating security challenges across multiple layers, including physical, network, application, and system dimensions. (1) This paper comprehensively surveys these security issues, systematically analyzing the threats encountered at each layer and proposing targeted countermeasures to mitigate risks. (2) Furthermore, the paper explores future trends in IoV security, emphasizing the roles of 6G networks, blockchain technology, and digital twins in addressing emerging challenges. (3) Finally, based on a comprehensive review of current research and insights, this paper aims to serve as a foundational reference for advancing secure and sustainable IoV ecosystems.
传感、通信、计算与智能集成（ISCCI）是B5G和6G技术的一项关键进展，为车联网（IoV）带来了变革潜力。随着车联网系统在智能交通和自动驾驶中变得越来越不可或缺，这些系统在物理、网络、应用和系统等多个层面也面临着不断升级的安全挑战。（1）本文全面调查了这些安全问题，系统分析了各层遇到的威胁，并提出了针对性的对策以降低风险。（2）此外，本文还探讨了车联网安全的未来趋势，强调了6G网络、区块链技术和数字孪生在应对新出现挑战方面的作用。（3）最后，基于对当前研究和见解的全面回顾，本文旨在为推动安全、可持续的车联网生态系统提供基础参考。
