EU Roadmap for Post-Quantum Cryptography Contributions

This document is a technical report that outlines Telefónica's feedback on the EU Roadmap for Post-Quantum Cryptography (PQC), published in June 2025. It discusses the transformative opportunities presented by quantum technologies while highlighting the associated risks, particularly regarding cryptographic vulnerabilities. The report emphasizes the importance of proactive measures and early preparations for transitioning to PQC solutions. It critiques the current approach of consulting stakeholders post-adoption of the roadmap and stresses the need for stronger coordination with industry. Key proposals include the introduction of Security Bonds to fund communications resilience, the development of cryptographic inventory tools, and the establishment of guidelines for achieving crypto-agility in real-world systems. The report also outlines the necessity for clear deployment guidelines and the establishment of testbeds to validate PQC solutions. Overall, it aims to enhance the security and resilience of Europe’s digital infrastructure against quantum threats.
