Post‑Quantum Cryptography (PQC) Emerging as a Critical Control Gap in Enterprise Roadmaps
What Happened — A live webinar hosted by Thales, promoted by DataBreachToday, highlighted the accelerating convergence of artificial intelligence and quantum computing and the resulting cryptographic risk landscape. The presenters warned that today’s widely‑deployed public‑key algorithms (RSA, ECC) could become vulnerable to future quantum‑capable adversaries, exposing sensitive data if organizations do not plan a migration to post‑quantum cryptography (PQC). The session outlined why delaying PQC adoption widens the attack surface, described the emerging threat of “harvest‑now‑decrypt‑later” attacks, and offered a high‑level migration framework for enterprises.
Why It Matters for Trust & Control Assurance — The discussion spotlights a control‑objective gap in cryptographic protection; mapping PQC readiness to existing frameworks (e.g., NIST CSF 2.0) provides a single, auditable evidence point that satisfies multiple compliance regimes.
Who Is Affected — Any organization that relies on public‑key encryption for data‑in‑transit or data‑at‑rest, especially sectors handling regulated data (finance, health, government, SaaS).
Recommended Actions
- Conduct a cryptographic inventory and classify assets by sensitivity.
- Map current algorithms to the “Cryptographic Protection” control area in your framework of record (e.g., NIST CSF 2.0 Identify → Protect).
- Begin a PQC pilot on low‑risk systems to collect migration evidence and refine timelines.
Technical Notes
- Quantum‑capable attacks target RSA‑2048/ECC‑256; NIST’s PQC standardization process is in its final draft stage (Round 3).
- “Harvest‑now‑decrypt‑later” attacks exploit data captured today for future decryption once a quantum computer is available.
- No specific CVE is involved; the risk is strategic and technology‑driven.
