MULTIDOMAIN PRIVACY PRESERVING AUTHENTICATION IN VEHICULAR AD HOC NETWORKS USING BLOCKCHAIN TECHNOLOGY | |
Author Name Manish R C, Suriya Narayanan R, Sanjithkumar J and Kiruthiga R Abstract In the field of vehicle ad-hoc networks (VANETs), the integration of vehicular wireless communication technologies has substantially improved driving safety and facilitated intelligent transportation applications. However, current authentication techniques are primarily concerned with vehicle security inside a single administrative domain, ignoring the overarching oversight required in the complex intelligent transportation system. In response, this research proposes a unique multidomain vehicle authentication architecture that uses blockchain technology to generate distributed trust and promote cross-domain information sharing across various administrative domains. Our suggested pseudonym-based privacy-preserving authentication mechanism assures anonymity and traceability, meeting the demand for increased security in the intelligent transportation ecosystem. To improve authority monitoring and key escrow robustness, we propose a two-phase pseudonym distribution mechanism that is conducted cooperatively with the help of a roadside unit (RSU) proxy. Our scheme's effectiveness and practicality in multidomain scenarios are demonstrated through thorough security analysis and compared evaluations with existing methods. The feasibility and effectiveness of the suggested blockchain-based multidomain authentication strategy are further demonstrated by real-world experiments, which also highlight the scheme's potential influence on improving the security and privacy environment in automotive communication networks.
