A framework for securing Open Radio Access Networks (O-RAN) against classical and quantum threats integrates post-quantum cryptography (PQC) and other quantum technologies within a Zero Trust Architecture. This approach provides a phased roadmap for adopting quantum-resilient mechanisms to enhance O-RAN's confidentiality, authentication, and trust for future 6G networks.
Key insights
- O-RAN's inherent openness and disaggregation necessitate a Zero Trust approach, which can be significantly strengthened by integrating quantum-safe mechanisms.
- Post-Quantum Cryptography (PQC) is identified as the most immediate and foundational quantum-resilient solution, deployable as software upgrades on existing classical hardware.
- Advanced quantum technologies like QKD, QIA, QDS, and QML offer complementary and provably secure enhancements for high-value links, authentication, and sophisticated threat detection within O-RAN.
