Abstract
The rise of Vehicular Ad-hoc Networks (VANETs) improves transportation efficiency and security, but their openness and dynamics also expose them to security threats such as privacy leakage, communication attacks, and unreliable information dissemination. Based on this phenomenon, we propose an ECC-based CLAS scheme that offers the following advantages: (1) introduces linear structure invalid signature detection without the need for complex data structures; (2) eliminates bilinear pairing and reduces computational overhead; and (3) maintains robust security by proving unforgeability against adaptive attacks. Performance analysis shows that the scheme significantly improves signature and verification efficiency compared to existing schemes.
