Project: QUAS

Topic: Post-quantum computing 
Proposal title: A Quantum-Shielded Framework for Authentication in Communication Protocols
Duration: 2025-2026

QUAS will set a pathway for the integration of post-quantum cryptography (PQC) into modern communication protocols to ensure the long-term confidentiality, integrity, and authentication of digital communications in the quantum era. The project introduces a unified framework to embed NIST-recommended PQC algorithms (HQC, Kyber, Dilithium) into real-world protocols such as QUIC (HTTP/3) and SIP (VoIP), addressing the growing urgency of preparing critical infrastructures for quantum-resilient security. By extending open-source stacks such as quiche, Kamailio, and Linphone, QUAS enables measurable benchmarking of PQC performance in diverse communication contexts. The project assesses key parameters—latency, handshake duration, CPU load, and overall efficiency—under hybrid and quantum-only configurations, producing vital data for cryptographic agility and standardization. Through practical validation in secure VoIP and web communication environments, QUAS provides actionable insights into PQC integration feasibility, resource optimization, and interoperability.

EDENTIFY role

  • Leads the implementation and validation of PQC-enabled communication modules, focusing on secure signaling, interoperability, and real-time performance. The team will adapt and extend SIP signaling and transport layers within Linphone to integrate hybrid and quantum-safe authentication flows, ensuring compatibility and efficiency across heterogeneous systems. EDENTIFY will also establish the benchmarking testbed to evaluate post-quantum handshake performance, CPU load, and latency under various network configurations.

  • In addition to technical contributions, EDENTIFY coordinates communication, dissemination, and community engagement for QUAS, ensuring that results—code, datasets, and documentation—are released as open-source assets. Through webinars, developer outreach, and collaboration with standardization bodies, EDENTIFY will promote awareness, reproducibility, and uptake of quantum-safe technologies across the European cybersecurity ecosystem.
