Is OT ICS crypto Quantum Proof? Industry Quantum Risk
Verdict
OT/ICS environments often cannot rapidly adopt PQC. Quantum readiness is inventory, segmentation, secure remote access, and realistic exception timelines—not overnight PLC upgrades.
Overview
Many industrial protocols historically lacked strong crypto. Where crypto exists, it is often classical and vendor-locked.
Cryptographic profile
- Signatures: PLC/RTU identities where present, Engineering workstation certs, Historian and DMZ TLS
- Hash: Vendor-dependent
- Public-key exposure: Safety systems with rare maintenance windows.
- Vertical: energy
What breaks
Mitigations
- Purdue-model segmentation with crypto inventory at conduits
- Jump host and PAM controls
- Vendor roadmap pressure for new capital projects
