QLAP: A Quantum-Resilient Security and Privacy Framework for Dynamic Spectrum Access
Abstract
The widespread deployment of ultra-distributed computing infrastructure and the adoption of the edge-cloud continuum architecture create an ever-increasing need for spectrum access. Database-driven cognitive radio networks (DB-CRNs) are a promising avenue to addressing spectrum scarcity in the wireless access domain. Since DB-CRNs are a key component in emerging wireless access networks, they are expected to be future-proof, providing crucial quantum-resilient security and privacy. To this end, we propose QLAP, a post-quantum (PQ)-secure and privacy-preserving spectrum access framework for DB-CRNs that protects secondary user (SU) identity and location privacy while enabling verifiable proximity-backed location assurance and regulatory-compliant spectrum access under realistic adversarial settings, with demonstrated practical efficiency against both classical and quantum adversaries.
