Toward Quantum-Safe 6G: Experimental Evaluation of Post-Quantum Cryptography Techniques

Ananya Kudaloor, Adnan Aijaz

6G networks will require quantum-secure cryptography deployed across core infrastructure, edge nodes, resource-constrained IoT devices. Although post-quantum cryptographic (PQC) algorithms have been standardized by NIST, their practical deployability in bandwidth and latency limited wireless systems remains unclear. This paper presents a practical evaluation of NIST selected PQC schemes, including ML-KEM (Kyber), ML-DSA (Dilithium), and Falcon. Benchmarks conducted with OpenSSL and the OQS provider on heterogeneous platforms show that while computational performance is acceptable, ciphertext and signature size expansion significantly impact handshake reliability and bandwidth efficiency, particularly at the network edge. The results highlight key system-level trade-offs and motivate the need for PQC optimization and deployment-aware design for future quantum-secure 6G networks.

Authentication of the QKD classical channel through Post-Quantum Cryptography in a multi-site 5G/6G quantum-safe communication network

Asier Atutxa, Ane Sanz, Eire Salegi +3 more

Breakthroughs in the field of quantum computing are forcing society to adapt the systems it employs to future threats. Telecommunications networks are no exception, and technologies such as Quantum Key Distribution (QKD) have been developed to establish secure and confidential mechanisms for quantum-safe key distribution. However, the lack of flexibility and scalability of this technology hinders its implementation in 5G/6G networks. In this context, this paper presents the design and development of a QKD classical channel authentication system based on Post-Quantum Cryptography (PQC) algorithms for securing multi-site 5G/6G networks. It also presents the deployment in an experimental infrastructure with a 5G core securization use case, and a comprehensive validation and performance evaluation, measuring key parameters such as protocol timing, error rate, and keyrate. Results show that the PQC authentication offers a similar performance compared to the inflexible, vendor-specific authentication mechanism, obtaining Quantum Bit Error Rate (QBER) measurements ranging from 2.5% to 3.5% in both cases, while only reducing the keyrate 4.53% (from 525.27 bps to 501.44 bps).

Quantum-Safe Networks for 6G an Integrated Survey on PQC, QKD, and Satellite QKD with Future Perspectives

Shiang-Jiun Chen, Yi‐Hsueh Tsai

Quantum computing presents significant issues to the current cryptographic landscape, especially with the upcoming deployment of 6G networks. Traditional cryptographic algorithms, such as Rivest-Shamir-Adleman (RSA) and Elliptic Curve Cryptography (ECC), are vulnerable to quantum-based attacks, leading to the need for Post-Quantum Cryptography (PQC), Quantum Key Distribution (QKD), and Satellite-based QKD solutions. This paper offers a comprehensive review of these quantum-safe technologies, discussing their integration within the context of 6G networks. Key performance indicators (KPIs), scalability issues, and hybrid cryptographic solutions are analyzed, along with the potential of Satellite-based QKD in securing global communications. The paper also explores use cases in healthcare, financial services, defense, and autonomous systems, evaluating future research directions and issues in scaling these quantum-safe technologies across industries.
