Terminology

• Claimer:: A user which claims properties about themselves in the format of a CType. This could be a person which claims to have a valid driver’s license.

• Attester:: An entity which checks a user’s claim and approves its validity. This could be a Citizens Registration Office which issues drivers licenses.

• Verifier:: An entity which wants to check a user’s claim by checking the provided attestation.

• CType:: CTypes are claim types. In everyday language, they are standardised structures for credentials. For example, a company may need a standard identification credential to identify workers that includes their full name, date of birth, access level and id number. Each of these are referred to as an attribute of a credential.

• Attestation:: An approved or revoked user’s claim in the format of a CType.

• Delegation:: An attestation which is not issued by the attester directly but via a (chain of) delegations which entitle the delegated attester. This could be an employe of a company which is authorized to sign documents for their superiors.

Assumptions

• The claim which shall be attested is based on a CType and signed by the claimer.
• The Verifier trusts the Attester. Otherwise, the attestation is worthless for the Verifier
