Abstract

AI factories and cloud platforms are moving security, telemetry and I/O processing into DPUs, offload processors and silicon roots of trust. These devices produce signed measurements and attested telemetry that downstream security tools act on. An authentic hardware observation, however, is not necessarily an applicable one. Between observation and effect, a buffer can be rewritten, a descriptor slot reused, a queue reset, firmware replaced, or a request rewritten by a proxy.

This paper defines evidence-qualified observation-to-effect consistency. It checks whether an independent hardware observation still describes the exact operation that later produced a device or external effect, across processor memory, DMA ownership, descriptor occupancy, firmware epochs, device consumption, hardware telemetry and proxy transformation. The method uses three ingredients:

  • generation-qualified identity;
  • measurement coverage;
  • source dependency.

It returns CONSISTENT, INCONSISTENT or UNRESOLVED as a Strong-Kleene-style conjunction, so missing telemetry is never read as absence. Verdicts are observational conclusions, not execution authority.

The paper presents:

  • a seven-phase, forty-two-stage workflow;
  • twelve inventive steps;
  • six embodiments;
  • forty implementation checkpoints;
  • a synthetic laboratory in Python, Go and JavaScript (48 fixtures, 154 passing test executions, about 1 to 4.5 microseconds per in-memory evaluation), which is self-authored and not independently or field validated.

A companion industry-relevance section aligns the method with public roadmaps:

  • NVIDIA: BlueField-4, DOCA Argus telemetry, DOCA Flow, attested telemetry.
  • Google: Titanium offload processors, Titan, Caliptra root of trust for measurement, Confidential Computing.
  • Others: Microsoft Azure Boost DPU and Integrated HSM, AWS Nitro, AMD Pensando and Intel infrastructure processors.
