# AI verification proposal

A proposal built with the Proposal Explorer of the AI Verification Tech Map (https://trustbutveri.fyi/), from its records of 2026-10-09. Interactive version: https://trustbutveri.fyi/explorer/?mechanisms=M-0023,M-0010,M-0009,M-0020

How to read it: a claim is something one party wants to verify about another's AI hardware or software. A mechanism is a general technique for verifying claims; it is "aimed at" a claim when that is its direct purpose, and "supporting" when it contributes without being aimed at it. A claim is addressed when a mechanism in the proposal is aimed at it and is not excluded by the filters; addressed does not mean verified, so check that mechanism's development status, security evidence and findings. Definitions: https://trustbutveri.fyi/about/methodology/ (roles, properties and findings) and https://trustbutveri.fyi/about/readiness/ (development status).

## Filters

Filters apply to mechanisms only and describe the setting the proposal is for.

None set. Every mechanism on the map was available.

## Overview

One row per mechanism, read from its record. Open failures: critical / significant / minor. The last three columns are the editors' reading of what the verifier sees. Findings are grouped as known failures, scope limitations and open questions. Only known failures count as failures. Counts are an inventory of published findings, not a risk score.

## Claims

No claims chosen.

## Mechanisms

### Safeguard attestation

Hardware-signed evidence that an AI service sent a given response through its declared safeguard path, such as a wrapper that calls a guardrail classifier. ([Safeguard attestation](https://trustbutveri.fyi/mechanisms/safeguard-attestation/))

- Assessment: mechanism family.
- Development: Research demonstration (legacy code R2), assessed for attesting that a declared safeguard mediated a service's responses.
- Security evidence: Published security analysis. Independent evaluation: unassessed. Formal proof: unassessed. Deployment assurance: unassessed.
- Claims in this proposal: none of them.
- Threat model: semi-trusted prover. Hardware: existing features. Prover cooperation: required. Attack testing: analysis. Category: Cryptographic & computational.
- What the verifier sees: model weights depends; inputs and outputs depends; training data not involved. The enclave route signs hashes of the safeguard, request and response; a low-trust design has the verifier re-run and screen sampled requests itself.

### On-chip telemetry from timing, memory and performance counters

Uses on-chip measurements, such as task timings, whether data sits in chip memory, and performance counters, as evidence of what AI chips are running. ([On-chip telemetry from timing, memory and performance counters](https://trustbutveri.fyi/mechanisms/on-chip-telemetry/))

- Assessment: mechanism family.
- Development: Research demonstration (legacy code R2), assessed for workload evidence from GPU counters and timing, assuming authentic measurements.
- Security evidence: Published attack testing. Independent evaluation: unassessed. Formal proof: unassessed. Deployment assurance: unassessed.
- Claims in this proposal: none of them.
- Threat model: semi-trusted prover. Hardware: existing features. Prover cooperation: partial. Attack testing: red-teamed. Category: On-chip & hardware-enabled.
- What the verifier sees: model weights depends; inputs and outputs depends; training data depends. Counters do not read weights or data, but richer counters can leak secrets through side channels.

### Hardware-enabled guarantees (flexHEG) and guarantee processors

A proposed add-on for AI chips: an auditable guarantee processor, sealed in a tamper-protected enclosure, that would check and enforce agreed rules on chip use. ([Hardware-enabled guarantees (flexHEG) and guarantee processors](https://trustbutveri.fyi/mechanisms/flexheg-guarantee-processors/))

- Assessment: mechanism family.
- Development: Proposed (legacy code R1), assessed for checking and enforcing training-compute limits on chips, against adversaries up to states.
- Security evidence: Published security analysis. Independent evaluation: unassessed. Formal proof: unassessed. Deployment assurance: unassessed.
- Claims in this proposal: none of them.
- Threat model: adversarial prover. Hardware: new chip design. Prover cooperation: required. Attack testing: analysis. Category: On-chip & hardware-enabled.
- What the verifier sees: model weights hidden; inputs and outputs hidden; training data hidden. The guarantee processor sees the chip's traffic inside a sealed enclosure and reports only whether rules were kept.

### Remote detection of data centres

Remote detection locates large data centres and estimates their power capacity without site access, using satellite imagery, heat signatures and public records such as permits. ([Remote detection of data centres](https://trustbutveri.fyi/mechanisms/remote-detection-of-data-centres/))

- Assessment: mechanism family.
- Development: Proposed (legacy code R1), assessed for finding undeclared data centres above an agreed compute threshold.
- Security evidence: Published security analysis. Independent evaluation: unassessed. Formal proof: unassessed. Deployment assurance: unassessed.
- Claims in this proposal: none of them.
- Threat model: adversarial prover. Hardware: none. Prover cooperation: not required. Attack testing: analysis. Category: Remote & side-channel sensing.
- What the verifier sees: model weights not involved; inputs and outputs not involved; training data not involved. Works from outside the facility; it does not handle model data.

## Limits

**Open significant failures**

- Components outside the attested boundary (known failure, theoretical argument, in Safeguard attestation; https://trustbutveri.fyi/mechanisms/safeguard-attestation/evidence/flaws/4/) [1][2]. In the proof-of-guardrail experiments, the guardrail model and the agent's backend model were both reached through external APIs, and the authors leave the decision to trust those APIs to the verifier. The measured wrapper must also have no vulnerability that lets the unmeasured agent bypass the guardrail, for example by executing arbitrary commands inside the enclave. The code's README states that the enclave does not currently restrict the agent's arbitrary command execution, which could be used to bypass guardrails.
- Memory-bus interposition extracts attestation keys and forges attestations (known failure, demonstrated attack, in Safeguard attestation; https://trustbutveri.fyi/mechanisms/safeguard-attestation/evidence/flaws/5/) [1][4][7][8][9][10][11][12][13]. Inherited finding. Applies to variants using the affected Intel or AMD trust roots. PAL*M excludes physical attacks. A TDX-backed safeguard claim against a physical host attacker would be defeated, but these studies do not demonstrate a break of the AWS Nitro proof-of-guardrail prototype or of verifier-side recomputation. The TEE findings cover DDR5 attacks on Intel TDX, the H100 relay demonstration, DDR4 attacks on AMD SEV-SNP, and software-only SEV-SNP forgery before AMD's fixes. These are inherited hardware limits; a governance analysis explains why physical access matters in a treaty setting. Related finding: https://trustbutveri.fyi/mechanisms/tee-remote-attestation/evidence/flaws/1/.

  Response: Intel and AMD place the physical attack class outside their threat models, according to the researchers. AMD reports firmware fixes for RMPocalypse.

  Related mechanism: Hardware-enabled guarantees (flexHEG) and guarantee processors (R1, in the proposal). A tamper-protected enclosure around the chip is the proposed answer when the party that holds the hardware may attack it physically.
- Adversarially disguised fine-tuning partly evades classification (known failure, demonstrated attack, in On-chip telemetry from timing, memory and performance counters; https://trustbutveri.fyi/mechanisms/on-chip-telemetry/evidence/flaws/2/) [16]. Across 20 evasion strategy families in five monitor-evader rounds, the classifier's accuracy against the most challenging disguised workloads held out from training was 43–87%. White-box LoRA fine-tuning was the only evasion family detected less than half the time. The evaluation covered single nodes, PyTorch-level evasion and NVIDIA hardware.
- Counters leak information about protected workloads (known failure, theoretical argument, in On-chip telemetry from timing, memory and performance counters; https://trustbutveri.fyi/mechanisms/on-chip-telemetry/evidence/flaws/4/) [9][17]. Performance counters have been used as a side channel against TEEs, for example in CounterSEVeillance. NVIDIA disables performance counters in full confidential-computing mode, stating that they could provide an avenue for side-channel attacks. Richer counters for verification therefore pull against confidentiality.
- State attackers can likely defeat current secure enclosures (known failure, theoretical argument, in Hardware-enabled guarantees (flexHEG) and guarantee processors; https://trustbutveri.fyi/mechanisms/flexheg-guarantee-processors/evidence/flaws/1/) [19][21]. The flexHEG authors write that "nation-state attackers can likely compromise the best current secure enclosures", and that the marginal cost of circumvention per device is hard to estimate. RAND similarly judges that anti-tamper measures "would not be insurmountable for a determined and well-resourced adversary", although they raise costs and can reveal tampering.
- Firmware-only retrofits rely on Secure Boot, which fault injection can bypass (known failure, theoretical argument, in Hardware-enabled guarantees (flexHEG) and guarantee processors; https://trustbutveri.fyi/mechanisms/flexheg-guarantee-processors/evidence/flaws/2/) [19]. Part II notes that the most common attack on Secure Boot replaces the firmware and applies a voltage glitch while the signature is being checked. It also notes that sophisticated actors may use microprobing or laser voltage probing to read key registers.
- FLOP accounting can be laundered through external data (known failure, theoretical argument, in Hardware-enabled guarantees (flexHEG) and guarantee processors; https://trustbutveri.fyi/mechanisms/flexheg-guarantee-processors/evidence/flaws/4/) [19]. Results of earlier or parallel workloads could be hidden in the "external data" fed to a device, which would falsify the total FLOP count unless the inputs are explained or time delays are imposed.

**Scope limitations**

- Attestation shows a safeguard ran, not that it is effective (scope limitation, theoretical argument, in Safeguard attestation; https://trustbutveri.fyi/mechanisms/safeguard-attestation/evidence/flaws/1/) [1]. Proof of guardrail ensures that the guardrail executed, but the guardrail can still err or be jailbroken. Because the guardrail must be open source, a malicious developer can attack it with jailbreaks while still presenting a valid proof. In the authors' evaluation, Llama Guard 3 reached an F1 score of 0.56 on the unsafe class of the ToxicChat dataset. The authors state that proof of guardrail should not be interpreted or advertised as proof of safety.
- Selective attestation leaves traffic uncovered (scope limitation, theoretical argument, in Safeguard attestation; https://trustbutveri.fyi/mechanisms/safeguard-attestation/evidence/flaws/2/) [1][4][9]. Attestations are issued per response. In the prototype, the agent offers them when it receives high-stakes questions, so nothing shows that unattested traffic went through the same path. PAL*M's authors note that a prover could cherry-pick favourable executions, and suggest verifier-published nonces or requesting only session-level proofs. A governance analysis notes that auditors also need assurance that all activity is accounted for, since a host could start a second confidential virtual machine that bypasses monitoring.

  Related mechanism: On-chip telemetry from timing, memory and performance counters (R2, in the proposal). On-chip counters are a proposed route to evidence about everything a chip runs, including a second virtual machine that skips the safeguard.
- Measurements may omit behaviour-relevant configuration or runtime changes (scope limitation, theoretical argument, in Safeguard attestation; https://trustbutveri.fyi/mechanisms/safeguard-attestation/evidence/flaws/3/) [9]. Every component that influences inference behaviour must be covered by the launch measurement, including feature flags, environment variables and invocation arguments. A launch measurement also does not show that a program keeps running as measured if the kernel is later compromised.
- Software-read telemetry can be forged by the operator (scope limitation, theoretical argument, in On-chip telemetry from timing, memory and performance counters; https://trustbutveri.fyi/mechanisms/on-chip-telemetry/evidence/flaws/1/) [14][16]. NVML-based classification assumes trustworthy telemetry. Without a tamper-resistant read path, an authenticated telemetry channel and secure boot of the monitoring software, an operator who controls the full software stack could forge counter values. Monfared et al. start from the same premise: current GPUs expose little trusted telemetry and can be modified or virtualized.

  Related mechanism: Hardware-enabled guarantees (flexHEG) and guarantee processors (R1, in the proposal). A guarantee processor on the chip would give the tamper-resistant, authenticated telemetry path the flaw says is missing.
- Timing challenges do not identify the individual chip (scope limitation, theoretical argument, in On-chip telemetry from timing, memory and performance counters; https://trustbutveri.fyi/mechanisms/on-chip-telemetry/evidence/flaws/3/) [14]. GEMM and VDF challenges can be answered by identical GPUs elsewhere, and floating-point fingerprints distinguish GPU models, not individual devices. GPU virtualization adds timing leakage that prevents attributing compute use.
- Many important rules cannot be checked on-chip (scope limitation, theoretical argument, in Hardware-enabled guarantees (flexHEG) and guarantee processors; https://trustbutveri.fyi/mechanisms/flexheg-guarantee-processors/evidence/flaws/3/) [18][20]. Malicious intent "is not a technical property observable on-chip", and misuse depends on what is done with a computation's results. A guarantee processor cannot easily tell whether a network is the whole system or one expert in a mixture-of-experts system. Part III judges that a fully local ruleset "may not be entirely feasible" for the same reason.
- Coverage stops at flexHEG-equipped chips (scope limitation, open question, in Hardware-enabled guarantees (flexHEG) and guarantee processors; https://trustbutveri.fyi/mechanisms/flexheg-guarantee-processors/evidence/flaws/6/) [18][20]. Motivated actors will always be able to use some compute that is not flexHEG-equipped. Recalling existing consumer GPUs would likely be impractical, and reaching perfect coverage, or conclusively proving that no secret government data centres exist, would be "practically quite difficult".

  Related mechanism: Chip registries and manufacturing records (R1, not in the proposal). Accounts for which chips exist and who holds them.

  Related mechanism: Remote detection of data centres (R1, in the proposal). Looks for undeclared facilities that hold other chips.
- Facilities can be disguised or hidden (scope limitation, theoretical argument, in Remote detection of data centres; https://trustbutveri.fyi/mechanisms/remote-detection-of-data-centres/evidence/flaws/1/) [24]. Halstead and Larsen discuss two ways to hide a facility. One is to disguise it as a legitimate industrial site. The other is to build it underground, with cooling that avoids visible heat plumes. They note that the underground option requires bespoke engineering.
- Small sites may not be detectable (scope limitation, theoretical argument, in Remote detection of data centres; https://trustbutveri.fyi/mechanisms/remote-detection-of-data-centres/evidence/flaws/2/) [24][26]. Halstead and Larsen conclude that a sufficiently small covert project could not be ruled out with confidence. In their estimates, the chance of detection is lower for smaller sites. Krawec notes that small data centres in existing buildings may lack the distinctive features of large facilities.

  Related mechanism: Chip registries and manufacturing records (R1, not in the proposal). Accounts for chips from the fab onwards, which does not depend on a site being visible.

**Open questions**

- No quantified error rates or formal thresholds for timing primitives (open question, open question, in On-chip telemetry from timing, memory and performance counters; https://trustbutveri.fyi/mechanisms/on-chip-telemetry/evidence/flaws/5/) [14]. Monfared et al. state that false-positive and false-negative rates are not quantified and leave hardware-specific formal thresholds to future work.
- Supply-chain diversion and hidden backdoors (open question, open question, in Hardware-enabled guarantees (flexHEG) and guarantee processors; https://trustbutveri.fyi/mechanisms/flexheg-guarantee-processors/evidence/flaws/5/) [19][20]. Components could be diverted before a guarantee processor is added, and backdoors could be introduced during design or manufacturing. Open-source designs and physical scans of randomly selected chips are proposed as countermeasures. Part III proposes international oversight of production and extensive testing of a random sample of finished devices.

  Related mechanism: Chip registries and manufacturing records (R1, not in the proposal). Records each chip's identity and owner from the fab onwards, which bears on diversion before a guarantee processor is fitted. It does not address hidden backdoors.
- Search for unknown sites is undemonstrated (open question, open question, in Remote detection of data centres; https://trustbutveri.fyi/mechanisms/remote-detection-of-data-centres/evidence/flaws/3/) [26]. Krawec reports that telling data centres apart from other industrial facilities systematically is difficult. Automating detection would need large amounts of training imagery and a purpose-trained model. In Krawec's words, automated data-centre detection "remains primarily conceptual at present".

**Not yet demonstrated**

- Hardware-enabled guarantees (flexHEG) and guarantee processors: Proposed (legacy code R1), assessed for checking and enforcing training-compute limits on chips, against adversaries up to states
- Remote detection of data centres: Proposed (legacy code R1), assessed for finding undeclared data centres above an agreed compute threshold

**Need new chip designs**

## Possible additions

Mechanisms on the map, not in the proposal, that the records connect to an unaddressed or partly addressed claim, an open failure or a dependency. Pointers, not recommendations: each brings its own readiness level and findings, and none is claimed to close a failure.

- **Hardware-attested weight binding** (Operational use (legacy code R3), assessed for hardware-attested weight binding showing users that a service runs its committed weights)
  - Safeguard attestation waits on it: Safeguard evidence must be bound to the model actually served, which depends on model-identity attestation.
- **TEE remote attestation for AI workloads** (Operational use (legacy code R3), assessed for showing which software ran to a party that distrusts the operator holding the hardware)
  - Safeguard attestation waits on it: Frontier model inference typically needs several GPUs, GPU confidential computing is less mature than CPU support, and CPU inference, which an enclave prototype had to use, ran about 100 times slower than GPU inference.
  - Safeguard attestation waits on it: Trust rests on a small number of hardware vendors, and a per-CPU Intel attestation key has been extracted by physical attack.
  - On-chip telemetry from timing, memory and performance counters depends on it.
  - Hardware-enabled guarantees (flexHEG) and guarantee processors depends on it.
- **Tamper evidence for verifier devices** (Research demonstration (legacy code R2), assessed for detecting probing of proposed verifier hardware, using server and electronics prototypes as evidence)
  - Hardware-enabled guarantees (flexHEG) and guarantee processors waits on it: State-level attackers who hold the hardware can likely compromise the best current secure enclosures.
- **Chip registries and manufacturing records** (Proposed (legacy code R1), assessed for a checkable record of which chips were made and who declared owning them)
  - Hardware-enabled guarantees (flexHEG) and guarantee processors waits on it: Governing all relevant chips depends on knowing where they are, through chip registries and detection of undeclared facilities.


## Dependencies

**Missing prerequisites**

- TEE remote attestation for AI workloads (Operational use (legacy code R3), assessed for showing which software ran to a party that distrusts the operator holding the hardware), needed by Safeguard attestation, On-chip telemetry from timing, memory and performance counters and Hardware-enabled guarantees (flexHEG) and guarantee processors
- Hardware-attested weight binding (Operational use (legacy code R3), assessed for hardware-attested weight binding showing users that a service runs its committed weights), needed by Safeguard attestation
- Chip registries and manufacturing records (Proposed (legacy code R1), assessed for a checkable record of which chips were made and who declared owning them), needed by Hardware-enabled guarantees (flexHEG) and guarantee processors

**Shared foundations**

- TEE remote attestation for AI workloads, relied on by Safeguard attestation, On-chip telemetry from timing, memory and performance counters and Hardware-enabled guarantees (flexHEG) and guarantee processors

**Blockers**

- Safeguard attestation: No published design shows that all of a provider's traffic passes through the attested safeguard path; current evidence covers individual attested responses. (coverage & hidden compute) [1][9]
- Safeguard attestation: Frontier model inference typically needs several GPUs, GPU confidential computing is less mature than CPU support, and CPU inference, which an enclave prototype had to use, ran about 100 times slower than GPU inference. (performance & compatibility; waits on TEE remote attestation for AI workloads) [9][29]
- Safeguard attestation: Trust rests on a small number of hardware vendors, and a per-CPU Intel attestation key has been extracted by physical attack. (hardware trust; waits on TEE remote attestation for AI workloads) [7][9]
- Safeguard attestation: Safeguard evidence must be bound to the model actually served, which depends on model-identity attestation. (evidence binding; waits on Hardware-attested weight binding) [29][30]
- Safeguard attestation: No independent red-team or audit of a safeguard-attestation system has been published, and the available prototypes are described by their authors as proofs of concept that have not been stress-tested by a counterparty. (adversarial validation) [2][6]
- On-chip telemetry from timing, memory and performance counters: Shipping accelerators need a tamper-resistant, authenticated telemetry path. (hardware trust; waits on Hardware-enabled guarantees (flexHEG) and guarantee processors) [15][16]
- On-chip telemetry from timing, memory and performance counters: NVIDIA's full confidential-computing mode disables the hardware performance counters its profiling tools use, so telemetry that needs them conflicts with it. (privacy & leakage) [9][17]
- On-chip telemetry from timing, memory and performance counters: Continuous challenge puzzles cost power and throughput on production workloads. (performance & compatibility) [14]
- On-chip telemetry from timing, memory and performance counters: Evaluation has not gone beyond single nodes, framework-level evasion and one vendor's hardware. (adversarial validation) [16]
- Hardware-enabled guarantees (flexHEG) and guarantee processors: Integrated flexHEG needs substantial help from the accelerator manufacturer, and the authors estimate 3.7–7.9 years, from when the manufacturer starts work, for such hardware to displace other accelerators in frontier development. (access & governance) [19]
- Hardware-enabled guarantees (flexHEG) and guarantee processors: State-level attackers who hold the hardware can likely compromise the best current secure enclosures. (hardware trust; waits on Tamper evidence for verifier devices) [19][21]
- Hardware-enabled guarantees (flexHEG) and guarantee processors: Rival states would need to trust the design and manufacture of guarantee processors and enclosures, for example through open design, redundant processors from each side or oversight of production. (hardware trust) [18][20]
- Hardware-enabled guarantees (flexHEG) and guarantee processors: Restricting future rule updates would need a formal language for rules, which the authors judge most likely infeasible for early flexHEG versions. (protocol soundness) [18]
- Hardware-enabled guarantees (flexHEG) and guarantee processors: Governing all relevant chips depends on knowing where they are, through chip registries and detection of undeclared facilities. (coverage & hidden compute; waits on Chip registries and manufacturing records) [20]
- Remote detection of data centres: Wide-area, automated detection of data centres is not yet practical and needs large training datasets. (coverage & hidden compute) [26]
- Remote detection of data centres: No measured detection or false-alarm rates for finding undeclared facilities have been published. (adversarial validation) [24][26]
- Remote detection of data centres: Recent high-resolution imagery is costly, is limited by weather and needs trained analysts. (access & governance) [26]
