5.3.4 FAL3 for Subscriber-Controlled Wallets

Since assertions from a subscriber-controlled wallet always contain a reference to one of the wallet’s verification keys inside the signed attribute bundle from the CSP, subscriber-controlled wallets that run on a subscriber-controlled device are capable of issuing holder-of-key assertions if all of the requirements for holder-of-key assertions are met (see Sec. 3.15). These assertions MAY be used to reach FAL3 if all requirements for FAL3 are met (see Sec. 2.4).

The verification keys of a subscriber-controlled wallet on a hosted service do not meet the requirements for holder-of-key assertions on their own since the subscriber is not in control of the key material as they would be on a subscriber-controlled device. To reach FAL3, federation transactions with a subscriber-controlled wallet on a hosted service SHALL use either a holder-of-key assertion (see Sec. 3.15) or a bound authenticator (see Sec. 3.16). All requirements for FAL3 in Sec. 2.4 SHALL be met. For example, a holder-of-key assertion from a subscriber-controlled wallet on a hosted service could include the verification key of an authenticator separate from the wallet verification key. The subscriber would present this additional authenticator to the RP along with the wallet’s assertion.
