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 focus shifted towards the centralization of data management in VANETs, which traditionally relies on systems maintained by vehicle service providers [57,58]. The risks associated with such a setup were recognized, including system failures and protection disagreements [59,60]. To address these concerns, a blockchain-based architectural design was proposed that employs sovereign identity for enhancing the security of data and uses a multitier, capability-based authentication process [61,62].…”

This manuscript delineates the development of an avant garde dual-layer blockchain architecture, which has been meticulously engineered to augment the security and operational efficacy of vehicular ad hoc networks (VANETs). VANETs, which are integral to the infrastructure of intelligent transport systems, facilitate the critical exchange of information between vehicular nodes. Despite their significance, these networks confront an array of formidable security vulnerabilities. Our innovative approach, employing a dual blockchain framework—the event chain and the reputation chain—meticulously tracks network activities, thereby significantly enhancing the trustworthiness and integrity of the system. This research presents a transformative dual-layer blockchain architecture, which was conceived to address the intricate security challenges pervasive in VANETs. The architecture pivots on a sophisticated reputation assessment framework, thus leveraging the principles of Bayesian inference and the analytical rigor of historical data to markedly diminish observational errors, as well as elevate the accuracy of reputation evaluations for vehicular nodes. A salient feature of our methodology is the implementation of an attenuation factor, which has been deftly calibrated to modulate the impact of historical behaviors on current reputation scores, thereby ensuring their relevance and alignment with recent vehicular interactions. Additionally, the numerical threshold serves as an indispensable mechanism, thus establishing a definitive criterion for the early identification of potentially malicious activities and enabling the activation of proactive security measures to safeguard the network’s integrity. Empirical validation of our dual-layer blockchain model has yielded a remarkable 86% efficacy in counteracting malevolent behaviors, thus significantly outperforming extant paradigms. These empirical outcomes underscore the model’s potential as a vanguard in the domain of secure and efficient reputation management within VANETs, thereby heralding a substantial advancement in the sphere of intelligent transportation systems.

“…The rapid growth of blockchain applications is due to its advanced features of immutability, transparency, distribution, traceability, security and reliability [10]. Nakamoto first proposed blockchain technology in 2008 and designed a cryptocurrency scheme based on blockchain technology to achieve secure transfers between two parties, opening up a new field of vision to solve the information security problems of third-party institutions [11].…”

The rise of Industry 5.0 has led to a smarter and more digital way of doing business, but with it comes the issue of user privacy and security. Only when privacy and security issues are addressed, will users be able to transact online with greater peace of mind. Thus, to address the security and privacy problems associated with industry blockchain technology, we propose a privacy protection scheme for online financial transactions based on verifiable ring signatures and blockchain by comparing and combining the unconditional anonymity provided by ring signatures with the high integrity provided by blockchain technology. Firstly, we present an algorithm for verifying ring signature based on distributed key generation, which can ensure the integrity of transaction data. Secondly, by using the block chain technique, we choose the proxy node to send the plaintext message into the block chain, and guarantee the security of the asset transaction. On this basis, the designed scheme is subjected to a security analysis to verify that it is completely anonymous, verifiable and unerasable. The protection of user privacy can be achieved while enabling online transactions. Finally, it is shown that the proposed method is more effective and practical than other similar solutions in performance assessment and simulation. It is proved that the scheme is a safe and efficient online financial transaction ring signature scheme.
