【Abstract】Vehicle-to-Grid (V2G) networks are potential solutions to addressing energy and environmental challenges, although security remains a key concern. For example, attackers may seek to obtain private information from frequent electricity/service exchanges between electric vehicles (EVs) and smart grids (SG) in V2G networks. While there have been successful attempts in using ring signatures to achieve privacy-preserving payment and ensure reliable services in V2G many existing ring signature-based payment proposals has significant signature size. To address the aforementioned problem, we propose Emularis, an efficient multilayered linkable ring signature scheme with a logarithmic size. We also implement an anonymous payment scheme for V2G using Emularis. We then prove that Emularis guarantees security and privacy requirements through rigorous security analysis. Furthermore, our scheme significantly outperforms existing schemes in terms of communication and computation costs. Extensive experimental results indicate that our scheme is suitable for the deployment in V2G security-related applications.
