Attestation Collateral

Attestation collateral is the supporting data a verifier needs to validate hardware-backed evidence. For Intel DCAP, this includes certificate chains, certificate revocation lists, Trusted Computing Base information, and identities for quoting components.

Why collateral matters

An attestation quote is not verified in isolation. The verifier must establish that the quote was signed by genuine hardware, that the relevant certificates have not been revoked, and that the platform's security version satisfies policy.

Some collateral expires or is replaced as security updates are released. Stale collateral can therefore cause a valid environment to fail verification. Automata's Onchain PCCS makes this data available to smart contracts, while the DCAP Dashboard helps operators monitor and maintain it.
