Quantum computing is no longer a distant possibility as it is rapidly becoming a reality. This technological shift poses a serious challenge to the cryptographic foundations that currently secure digital communications, transactions, and sensitive data.
To help organisations in Belgium prepare for this disruption, the Centre for Cybersecurity Belgium (CCB) has contributed to a white paper on Post-Quantum Cryptography (PQC). This initiative was led by the Belgian Cyber Security Coalition and the Quantum Circle, and brings together experts from across sectors to provide practical guidance for quantum-safe resilience.
The white paper outlines:
- The quantum threat and its implications for long-lived and sensitive data.
- The concept of “harvest now, decrypt later”, where encrypted data collected today may be decrypted in the future.
- The EU strategic roadmap with milestones: national strategies by 2026, critical infrastructure protected by 2030, and broad adoption by 2035.
- Sector-specific use cases in telecom, banking, healthcare, and retail.
- The importance of crypto-agility — the ability to adapt cryptographic systems quickly and securely.
For Belgian organisations, this is not just a technical challenge. It is a matter of business continuity, regulatory compliance, and digital trust. Early action will reduce complexity, cost, and risk and position organisations as leaders in cybersecurity resilience.
