Notes on proving the machine.

Perspectives on sovereign AI, silicon-rooted identity, component-level provenance, counterfeit detection, and the trust layer beneath AI infrastructure.

Machine learning under attack: where silicon-rooted identity stops the threat

The ML attack surface spans the model, the data, and the infrastructure. Hardware-rooted identity shuts down a whole class of infrastructure and provenance attacks — model theft, substitution, rogue hardware, repudiation — and composes with model-level defenses for the rest.

US assembly isn't enough: the case for component-level provenance

The FCC just closed the "component part loophole." Verifying where a device was assembled no longer proves it's clean — a logic-bearing part from a Covered List entity can hide inside an otherwise US-built device. Proving genuineness component by component is a harder, and more important, problem.

An ePassport for machines

Border control solved impostor identity with a chip that can't be forged and can be checked anywhere. AI infrastructure faces the same question at every node — and needs the same kind of answer.

Counterfeit detection for AI hardware

A cloned credential and a counterfeit chip look identical to software. When identity comes from the physics of the specific device, a genuine machine and an impostor stop looking the same.

Prove the machine, not just the workload

Confidential computing protects what runs, in memory, while it runs. It doesn't prove which enrolled machine ran it, under whose authority, or hold evidence you can check tomorrow. That's a different layer — and UBIQS composes with it.

A receipt for every execution

The portable, tamper-evident record that ties the physical node, the model, and the policy to a result — and turns "trust us" into evidence an auditor can verify long after the job is gone.

Identity you can't copy

Certificates, API keys, and tokens are data — and data gets copied, extracted, and replayed. Why the only machine identity that holds under pressure is one derived from physics, not assigned by an authority.
