“…Unfortunately, the use of conventional PKI systems makes the system more expensive because the use of the same certificates would break the unlinkability requirement. Furthermore, the authors in [16] proposed the utilisation of self-blindable certificates to enable anonymous communications, ensuring that the contact remains untraceable using a single valid certificate. Furthermore, the examination of data is of utmost significance.…”

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 introduction and usage of VANETs in real world scenarios also brought by privacy concern because of the continuous exchange of location and other sensitive information among vehicles and infrastructure components. Protecting the privacy of individuals in VANETs is essential to encourage widespread adoption and prevent potential misuse of personal data [179], [180]. Vehicles should trust the sender that may have an identity or not, as well as trust the intermediate forwarder vehicles.…”

Vehicular Ad-Hoc Networks (VANETs) is a type of mobile ad hoc network (MANET) specifically designed for communication among vehicles on the road. VANETs enable vehicles to communicate with each other and with roadside infrastructure, forming a dynamic and self-organizing network without the need for a fixed communication infrastructure. Security concerns in VANETs encompass a range of threats, including Authentication and Authorization attacks, Sybil attacks, Denial-of-Service incidents, Location spoofing, and Eavesdropping. Privacy, on the other hand, is a paramount concern in VANETs due to the sensitive nature of location-based data, Identity Disclosure, and user consent Control. The paper emphasizes the necessity for robust security mechanisms and outlines specific requirements for safeguarding VANETs. Proposed mitigation measures, including cryptographic techniques and authentication mechanisms, are critically assessed for their effectiveness and feasibility. The findings provide a comprehensive understanding of the complexities surrounding privacy and security in VANETs, contributing valuable insights for the development of resilient and privacy-preserving vehicular communication systems.

“…The intelligent transportation system (ITS) integrates a variety of advanced equipment and technologies and has gradually become an important part of the next generation of urban transportation, providing convenience for drivers and passengers [1]. Vehicular ad hoc networks (VANETs), as the key parts of ITSs, adopt dedicated short-range communication technology (DSRC) and enable rapid interconnection between vehicle-to-vehicle (V2V) and vehicle-to-roadside infrastructure (V2I) to ensure that drivers and passengers have access to continuous and reliable services and applications [2]. In order to preserve vehicle identity privacy, VANETs mandates that vehicles utilize pseudonyms instead of real identities to anonymize identities and regularly change pseudonyms to prevent tracking from adversaries [3].…”

IMF-PR: An Improved Morton-Filter-Based Pseudonym-Revocation Scheme in VANETs

Vehicle ad hoc networks (VANETs) are special wireless networks which help vehicles to obtain continuous and stable communication. Pseudonym revocation, as a vital security mechanism, is able to protect legal vehicles in VANETs. However, existing pseudonym-revocation schemes suffer from the issues of low certificate revocation list (CRL) generation and update efficiency, along with high CRL storage and transmission costs. In order to solve the above issues, this paper proposes an improved Morton-filter-based pseudonym-revocation scheme for VANETs (IMF-PR). IMF-PR establishes a new distributed CRL management mechanism to maintain a low CRL distribution transmission delay. In addition, IMF-PR improves the Morton filter to optimize the CRL management mechanism so as to improve CRL generation and update efficiency and reduce the CRL storage overhead. Moreover, CRLs in IMF-PR store illegal vehicle information based on an improved Morton filter data structure to improve the compress ratio and the query efficiency. Performance analysis and simulation experiments showed that IMF-PR can effectively reduce storage by increasing the compression gain and reducing transmission delay. In addition, IMF-PR can also greatly improve the lookup and update throughput on CRLs.
