Full Title or Meme
A statement is Attested if some Trusted Third Party can create a Validated Claim about a User Device used during either Authentication or Authorization.
Context
- The Context in which an Attestation of Identity applies is typically during the Validation of the security of protection offered to User secrets (such as Credentials) in a User Agent.
Problem
- When a secure operation is performed at a user location, the packet returned from that User Device needs to be trusted by the Site that receives it.
- The signing key for that packet will have a certificate that binds that signing key to a particular device.
Solution
- The certificate for the signing key from the User Device, and potentially the configuration information from the device, will need to be Attested by some Trusted Third Party.
- Attestation can be complex for programmable computers, or simple for one function User Devices like Security Tokens.
- An example of a single attestation program with associated metadata is described in the FIDO web site.
- When a simple certificate is used, it typically is accompanied by a metadata statement, an example is this one at Yubico.
References
- Synonyms include: Assured Corroborated Validated.
