What Does Cryptography Post-Quantum Look Like? The European Commission Has Released New Recommendations

A prominent topic of discussion regarding quantum technology and quantum computing is its impact on cryptography. However, it's not all negative from a technological standpoint. In fact, quantum-based cryptography has been in development for the past decade and would enhance the overall security of the world's data. The question then arises: How should this technology be developed? Building on the experiences of the past year with the wide-scale deployment of AI followed by recent regulatory creations, policymakers are striving to be at the forefront of regulations regarding quantum technology. This week, the European Commission released their recommendations for developing a roadmap to quantum cryptology.

Cybersecurity stands as an essential component of Europe's existence in the digital age and is a key pillar of their Digital Decade policy programme. To ensure stronger safeguards and the protection of sensitive communications, the commission recommends switching to "Post-Quantum Cryptography" as soon as possible. This switch would eliminate current vulnerabilities of asymmetric cryptography and enhance protection against threats posed by quantum computers. The commission itself has been funding quantum cryptography research and development for the past decade and is now calling on Member States to do the same.

In my opinion, the most critical aspect of the recommendation was the emphasis on creating a roadmap. This approach facilitates a smoother transition over the coming decade to quantum cryptography. The roadmap should define common security goals and progress pathways, along with a timeline for transition. It should also consider how quantum cryptology can integrate with current systems in hybrid environments. Each step should delineate the required actions for each Member State and involve key stakeholders. Additionally, Member States can collaborate with the commission in evaluating and selecting developing quantum algorithms to ensure harmonization of the new quantum cryptography strategy across the EU. The commission plans to closely monitor the progress in creating the roadmap, along with the individual responsibilities of each Member State.

This recommendation ensures that policymakers are at the forefront, ensuring a smoother implementation of quantum technologies into current infrastructure.

It is expected that as quantum technology continues to expand its applications, threats to current systems and infrastructure will emerge. It is the responsibility of groups like the European Commission to support progress while ensuring the security of people as well.
