Popis:	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 \emph{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.
