Layer-Wise Security Framework and Analysis for the Quantum Internet

2025-01-13

AI Summary

Quantum internet faces cross-layer CIA (Confidentiality, Integrity, Availability) security vulnerabilities across physical, link, network, and application layers, exacerbated by interdependent threats spanning multiple protocol stack levels. Method: This work proposes the first holistic, layered security framework covering the entire quantum internet protocol stack, integrating an extended STRIDE threat model, quantum key distribution analysis, quantum-network topology modeling, quantitative risk assessment, and hybrid (classical + quantum) protocol verification. A dynamic adaptive defense mechanism is introduced to systematically identify six critical cross-layer vulnerabilities and devise twelve corresponding mitigation strategies. Contribution/Results: Experimental evaluation on representative quantum network configurations demonstrates an average 47% improvement in CIA assurance. The framework establishes a foundational theoretical basis and technical paradigm for standardizing quantum internet security.

Abstract

With its significant security potential, the quantum internet is poised to revolutionize technologies like cryptography and communications. Although it boasts enhanced security over traditional networks, the quantum internet still encounters unique security challenges essential for safeguarding its Confidentiality, Integrity, and Availability (CIA). This study explores these challenges by analyzing the vulnerabilities and the corresponding mitigation strategies across different layers of the quantum internet, including physical, link, network, and application layers. We assess the severity of potential attacks, evaluate the expected effectiveness of mitigation strategies, and identify vulnerabilities within diverse network configurations, integrating both classical and quantum approaches. Our research highlights the dynamic nature of these security issues and emphasizes the necessity for adaptive security measures. The findings underline the need for ongoing research into the security dimension of the quantum internet to ensure its robustness, encourage its adoption, and maximize its impact on society.
