AMORT-V1 reduces post-quantum attestation costs for industrial controllers
Original title: AMORT-V1: Checkpointed Post-Quantum Attestation for Industrial Controllers
Checkpointed protocol cuts signing and commitment overhead by up to 878 times versus per-report methods.
AMORT-V1 moves public-key signing and durable commitments to periodic checkpoints for programmable logic controllers. Devices use MACs for reports and a disclosure chain for origin proof. Testing on Raspberry Pi 5 shows 90x and 878x cost reductions with durable logging.
- 90 times lower controller cost without durable logging
- 878 times lower with durable logging required
- 2.95 micro sec per report for transferable verification
- TPM-backed monotonic state for rollback resistance
From the original article
1 min read at arxiv.orgProgrammable 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.
