Title: An efficient multilayered linkable ring signature scheme with logarithmic size for anonymous payment in vehicle-to-grid networks

 

Journal: IEEE Transactions on Intelligent Vehicles

 

Abstract: Vehicle-to-Grid (V2G) networks are emerging as an outstanding technique for alleviating energy and environmental concerns. Whereas, malicious attackers thirst for private information from frequent electricity/service exchanges between electric vehicles (EVs) and smart grids (SG) in V2G networks. Several attempts have been made to use ring signatures to achieve privacy-preserving payment and ensure reliable services in V2G. Nevertheless, most of the existing ring signature-based payment proposals may still have numerous limitations in the V2G paradigm due to their heavy signature size. To address the aforementioned problem, we propose Emularis, an efficient multilayered linkable ring signature scheme with a logarithmic size. Specifically, we 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 deployment in V2G security-related applications.
