Quantum Security Deadlines are Here – What Happens Next?

AI-summarised brief · reviewed before publication

Governments have set timelines to phase out RSA and ECC by 2035, with full migration to post-quantum cryptography expected. The transition applies to public sector systems, contractors, and industries handling regulated data. NIST guidance indicates deprecation by 2030 and disallowance by 2035. The NSA requires quantum-resistant cryptography for new acquisitions starting in 2027, with the European Union outlining similar timelines, particularly for critical infrastructure, by 2035.

💡 Why It Matters

  • · Early migration is crucial as delayed transitions may leave systems vulnerable to quantum attacks.
  • · Regulatory pressure from frameworks like NIS2 and DORA reinforces the need for cryptographic agility.
