This study provides an architectural framework and a comprehensive examination of how the combination of threshold key management, privacy-enhancing technologies (e.g., homomorphic encryption, secure multi-party computation), and decentralised ledger technologies (DLT) enhances the security and privacy of vehicle ad-hoc networks (VANETs). We also examine the challenges of existing VANET structures, with a particular focus on trust, privacy, and scalability concerns. Our proposed architecture shifts from centralised to decentralised systems, highlighting the advantages of a decentralized ledger framework, specifically in ensuring the robustness, strong availability, integrity, and resilience of data against various cyber security threats. The architecture uses Layer 2s instead of Layer 1s as Layer 2s is much cheaper and faster. Furthermore, we explore how the aforementioned advanced cryptographic mechanisms are utilized in VANETs for improving key management, the distribution of trust, and data privacy, together with privacy-preserving data analysis, aiming to achieve resilient vehicle-to-everything (V2X) communication and privacy-preserving data analysis. We conclude by highlighting potential future directions for more secure, efficient, and resilient VANET systems in the era of 5G and beyond.

“…The diverse security requirements of connected, intelligent, and autonomous vehicles call for a systematic and robust approach that integrates and facilitates seamless interaction among solutions [11]. In contrast to today's widespread in-vehicle security measures, a hierarchical self-aware cybersecurity architecture consisting of real-time security monitoring, analysis, decision-making, and visualization layers is due for this transition.…”

“…Proceeding with these security measures follows the reporting measures that archive each decision taken to the BlackBox with the help of agents. The classified input data that pass the security checks proceed to the next decision phase visible in Algorithm 1, Lines (6)(7)(8)(9)(10)(11)(12)(13)(14). The outcome of this decision forwards data to the next phase or rejects/drops failed messages.…”

The inherent dynamism of recent technological advancements in intelligent vehicles has seen multitudes of noteworthy security concerns regarding interactions and data. As future mobility embraces the concept of vehicles-to-everything, it exacerbates security complexities and challenges concerning dynamism, adaptiveness, and self-awareness. It calls for a transition from security measures relying on static approaches and implementations. Therefore, to address this transition, this work proposes a hierarchical self-aware security architecture that effectively establishes accountability at the system level and further illustrates why such a proposed security architecture is relevant to intelligent vehicles. The article provides (1) a comprehensive understanding of the self-aware security concept, with emphasis on its hierarchical security architecture that enables system-level accountability, and (2) a deep dive into each layer supported by algorithms and a security-specific in-vehicle black box with external virtual security operation center (VSOC) interactions. In contrast to the present in-vehicle security measures, this architecture introduces characteristics and properties that enact self-awareness through system-level accountability. It implements hierarchical layers that enable real-time monitoring, analysis, decision-making, and in-vehicle and remote site integration regarding security-related decisions and activities.

“…However, it should be noted that some of the potential vulnerabilities identified by the automated scanning tool may not represent real vulnerabilities in the context of the system environment. The open and vulnerable nature of the ITS underlying communication infrastructure needs sophisticated security mechanisms to assure a safe real-life deployment [2]. Some of the common security vulnerabilities in toll collection systems include: 1.…”

Security vulnerabilities in toll collection systems can pose significant risks to the integrity of these systems. These vulnerabilities can include unauthorized access to sensitive information, tampering with electronic payment systems, and disruption of communication between vehicles and roadside infrastructure. Furthermore, the complexity of toll collection systems and the increasing reliance on electronic payment technologies introduce additional potential vulnerabilities. These vulnerabilities highlight the importance of implementing robust security measures to protect toll collection systems and ensure the privacy and safety of users.
