AMORT-V1: Checkpointed Post-Quantum Attestation for Industrial Controllers
Checkpointed post-quantum attestation for PLCs cuts signing latency that previously consumed up to 99 % of round-trip time, making quantum-resistant integrity verification viable for long-lived industrial controllers.

arXiv:2611.07476v1 Announce Type: new Abstract: Programmable logic controllers often remain deployed for decades, making post-quantum attestation a long-term requirement. Prior measurements of OpenPLC attestation show that post-quantum signing can consume 88--99% of round-trip latency and that durable state can further limit throughput. We introduce AMORT-V1, a checkpointed attestation protocol that moves public-key signing and durable commitment from individual reports to periodic checkpoints.
Editorial Analysis
PLCs in European utilities and manufacturing often run for decades; post-quantum attestation that fits real-time constraints gives operators a credible migration path before quantum threats materialise.
Include post-quantum attestation latency testing in your OT crypto-agility roadmap to identify controllers that need hardware refresh.
Industrial controllers deployed for decades need quantum-resistant integrity checks — new research makes that feasible within real-time constraints.
