Mission-Aware Attestation Envelopes for Time-Critical Autonomous Action: A Hardware-in-the-Loop V2I Study

Summary

The paper proposes mission-aware attestation, a runtime assurance contract for autonomous systems that requires valid integrity, fresh evidence and a decision within a budget set by the physical state. It separates four refusal outcomes where a binary gate gives two. Hardware-in-the-loop vehicle-to-infrastructure tests show a hardware-informed model admits three quarters of the operating space, and the attestation interval is identified as the directly configurable deployment parameter.
