v[apor]TPM

Cloud vTPM attestation library for Rust. Zero C dependencies.

What does the "v" in vTPM stand for?

Physical TPM trust is vapor. It evaporates under scrutiny - supply chain attacks, firmware vulnerabilities, the whole theater. The only meaningful TPM trust lives in cloud vTPMs, where the hypervisor is the root of trust. The "v" always stood for vapor. Everyone just forgot.

Crates

CrateDescription
vaportpm-attestGenerate attestations - talks to TPM
vaportpm-verifyVerify attestations - no TPM needed

Trust Model

The verifier handles cryptographic verification:

  • Validates signatures and certificate chains
  • Identifies the cloud provider via embedded root CA hashes

You handle policy decisions:

  • Do the PCR values match known-good measurements?
  • Is the nonce fresh (replay protection)?

Supported Platforms

PlatformStatusTrust Anchor
AWS EC2 with Nitro v4+✅ WorkingNitro Root CA
GCP Confidential VM✅ WorkingGoogle EK/AK CA Root
Azure Trusted Launch🔜 PlannedMicrosoft AK certificate

Please note that GCP 'Shielded VM' with vTPM isn't enough, a 'Confidential VM' is necessary as Google doesn't provision AK certificates without that feature enabled (be it Intel TDX or AMD SEV)

Quick Start

Generate Attestation (on cloud instance)

use vaportpm_attest::attest;let json = attest(b"challenge-nonce")?;// Send json to verifier

Verify Attestation (anywhere)

use vaportpm_verify::verify_attestation_json;let result = verify_attestation_json(&json)?;// Verification succeeded - attestation is from a supported cloud providerprintln!("Provider: {:?}", result.provider);println!("PCRs: {:?}", result.pcrs);
