3.17 RP Processing of Holder-of-Key Assertions and Bound Authenticators

When the RP receives an assertion that is associated with a bound authenticator, the subscriber proves possession of the bound authenticator directly to the RP. The primary authentication at the IdP and the federated authentication at the RP are processed separately. While the subscriber could use the same authenticator during the primary authentication at the IdP as the bound authenticator at the RP, there is no assumption that these will be the same.

The following requirements apply to all assertions that are associated with a bound authenticator:

The subscriber SHALL prove possession of the bound authenticator to the RP in addition to presenting the assertion itself.
For a holder-of-key assertion, a reference to a given authenticator that is found within an assertion SHALL be trusted at the same level as all other information within the assertion, as stipulated in the trust agreement.
The RP SHALL process and validate the assertion in addition to the bound authenticator.
Failure to authenticate with the bound authenticator SHALL result in an error at the RP and SHALL NOT create an authenticated session at the RP.
