PAI-SF / 3 / PAI-SF-ATT-002

Hardware Provenance and Anti-Tamper

Objective

Verify physical hardware components have not been substituted or tampered with post-manufacture.

Hardware bill of materials with cryptographic provenance markers; physical tamper-evidence mechanisms.

Systems where hardware substitution or tampering could affect physical safety.

HBOM documentation; tamper-inspection records. [T2]

Evidence of periodic physical inspection, not only design-time documentation.

PAI-SF-SUP-001 (Domain 9, component provenance) — closely related but ATT-002 is the physical/tamper- detection layer specifically.

Not applicable to components with no plausible physical-substitution attack surface.

Expected at Operational and High-Assurance levels.

Provides hardware-tampering incident categories for UAIF™; defines re-provisioning procedures for AI- IRF™.
