What is Cryptographic attestation?
Cryptographic attestation is signed evidence about a device, software measurement, or system state, evaluated against a trust policy. It can support a claim about how a component was provisioned or executed, but its meaning depends on the issuer, evidence scope, freshness, and verifier.
A relying system should validate the signature chain, nonce or freshness challenge, measurement policy, and revocation information. Attestation does not establish that an application is free of bugs or that an authorized transaction is economically safe.
Document exactly what the attestation covers and what it leaves out. Trust decisions should use a maintained policy and an explicit failure path when the evidence is missing, expired, or unverifiable.
