QS-BTrust: A Quantum-Secure Privacy-Preserving Protocol With Revocation for Trusted Broadcasting in Integrated Vehicular Networks

Published
Record updated

Summary

This paper proposes QS-BTrust, a quantum-secure, privacy-preserving authenticated broadcast protocol for Integrated Vehicular Networks. It combines Physical Unclonable Functions, post-quantum digital signatures, and Hashgraph-based authentication tag management. The authors analyze it under the Dolev–Yao adversary model, validate it with ProVerif, and assess it under the Random Oracle Model and Quantum Random Oracle Model, reporting lower verification overhead under high message loads than representative schemes in simulation.
