Quantum-Agile 5G Core / QA5G
Quantum-Agile 5G Core / QA5G
This proposal aims to enhance the security of 5G Service-Based Architecture (SBA) by integrating post-quantum cryptographic algorithms through libOQS. Specifically, QA5G will replace traditional cryptographic mechanisms in key services such as NRF and AUSF with quantum-resistant protocols, ensuring protection against future quantum attacks. The project will also focus on TLS-based communication within the SBA, demonstrating cryptographic agility and long-term resilience in 5G infrastructure.
Use case 1 winner
Analysis and Optimisation of PQC Algorithms for Firmware Signing / QA5G
The project evaluates PQC algorithms for firmware signing, focusing on ML-DSA, SLH-DSA, Falcon, LMS. It benchmarks their performance against classical cryptographic methods (e.g., NIST P-256) in terms of signing time, verification time, and signature size. The goal is to address the challenges of migrating to PQC, explore hybrid deployments, and optimize PQC for efficient, scalable firmware updates. The optimised usecases will then be implemented as proof of concept.
Use case 4 winner
QUIET – QRISP for Measuring the Security of Lattice-Based Cryptosystems
The proposed project aims to study the effects that the different parameters defining a lattice may cause in the security of cryptographic schemes based on them. Considering the state-of-the-art attacks to those schemes, the goal is to build a tool using QRISP that, given some lattice parameters, outlines the security of the underlying schemes.
