Privacy-preserving authentication scheme for electricity trading in V2G network using anonymous credential and blockchain
To address privacy leakage issues in traditional V2G power transaction authentication, including identity forgery, transaction behavior analysis, and location tracking, a blockchain-based privacy-preserving authentication scheme for V2G networks was proposed. The scheme designed anonymous credential...

| description | To address privacy leakage issues in traditional V2G power transaction authentication, including identity forgery, transaction behavior analysis, and location tracking, a blockchain-based privacy-preserving authentication scheme for V2G networks was proposed. The scheme designed anonymous credentials incorporating CL signatures and zero-knowledge proofs to achieve identity authentication without exposing sensitive information. Secure and decentralized authentication mechanisms were embedded into blockchain infrastructure to eliminate reliance on trusted third parties, thereby preventing EV privacy exposure during transaction authentication while enhancing resistance against internal and external security threats. Secure traceability was realized for EV charging/discharging transactions. Security analysis and performance evaluation demonstrated that the proposed scheme effectively protects EV privacy in power transactions, with computational and communication overhead shown to meet real-time requirements. The results indicate that the integration of cryptographic primitives and distributed ledger technology establishes a balanced equilibrium between privacy preservation and system accountability in V2G ecosystems. |
