Quantum-Secure Certificate-Less Conditional Privacy-Preserving Authentication for VANET
arxiv(2024)
摘要
Vehicular Ad-hoc Networks (VANETs) marked a pronounced change in the
Intelligent Transport System and Smart Cities through seamless vehicle
communication to intensify safety and efficacy. However, a few authentication
schemes have been devised in the literature to ensure the authenticity of the
source and information in the post-quantum era. The most popular base for such
construction is lattice-based cryptography. However, existing lattice-based
authentication schemes fall short of addressing the potential challenges of the
leakage of the master secret key and key-escrow problem. By ingeniously
addressing both issues, the paper proposes the first quantum secure
authentication scheme to eliminate the flaws while maintaining the system's
overall efficiency intact. Compared to the state-of-the-art schemes, the
provable security and overall performance assessment highlight the suitability
of the proposed approach.
