Abstract

This research paper presents a framework, referred to as QRAPSF, which is quantum-resilient and adaptive privacy security framework for 6G communication systems. The QRAPSF framework incorporates quantum-resistant key establishment using ML-KEM, authentication using ML-DSA, lightweight privacy preserving identity management, adaptive physical layer security, and threat aware security level selection. The hierarchical security controller determines the appropriate security level based on channel status, device capability, latency requirements, and threat level. The proposed QRAPSF framework obtains attack detection accuracy of 96.24%, authentication success rate of 98.31%, and privacy preservation efficiency of 95.14% under 5% network load and 93.81%, 96.19%, and 92.61%, respectively, under 30% network load. The communication overhead remains between 9.42% and 11.68%, whereas the authentication latency varies between 29.84 ms and 37.42 ms depending on the network load. Under 30% network load, the proposed QRAPSF framework has communication overhead 5.40 percentage points less than that of Lattice-Based Physical Layer Security and authentication latency 7.86 ms less than that of Hybrid PQC Authentication.
