An Efficient Multi-Level and Cross-Domain Conditional Anonymous Authentication Scheme in V2G
- Published
- Record updated
Summary
Researchers propose a multi-level, cross-domain conditional anonymous authentication scheme for vehicle-to-grid (V2G) systems, aimed at protecting electric vehicles' privacy during cross-domain authentication. The design uses group signatures with a group key generated via the Chinese Remainder Theorem for grid servers, and proxy signatures for vehicles, plus online/offline signatures to improve efficiency. The authors report lower computational, communication, and storage costs than existing schemes and claim security through a formal security model and analysis.
