Abstract: The Internet of Vehicles (IoV) has emerged as a transformative technology in Intelligent Transportation System (ITS), enabling seamless connectivity between vehicles, infrastructure, and devices. However, as IoV systems evolve, they face complex security and privacy challenges, especially in light of increasing connectivity, data sharing, and the integration of 6G networks. Existing security solutions, including blockchain-based schemes and authentication protocols, often struggle with scalability, resource efficiency and latency requirements. This survey systematically reviews the landscape of privacy-preserving and secure IoV solutions, assessing recent advancements in cryptographic techniques, decentralized trust management, and emerging quantum-resistant protocols. By identifying significant research gaps this paper highlights areas where future research can innovate to meet IoV’s demanding security and privacy needs. The findings aim to guide the development of robust, adaptive solutions for secure, high-speed, and privacy-conscious IoV networks in an increasingly connected vehicular ecosystem.
