Relying Parties

Control

In the context of a PIV federation, a subscriber logs into the RP using the federation protocol to use the RP’s services and functionality. The nature of the services provided by the RP and the nature of the RP’s deployment are outside the scope of this document. General requirements for the RP in a PIV federation are discussed in Sec. 5.3 , and general requirements for RPs in all federation contexts are discussed in [SP800-63C] .

In PIV federation, the RP does not directly verify the authentication of the PIV credential, nor does the RP manage the PIV identity account. The RP’s only view into the contents and status of the PIV identity account comes through its interactions with the IdP. The RP can manage its own local reference to the PIV identity account along with information that is local to the RP. This record is known as the RP subscriber account and is defined by [SP800-63C] and discussed in Sec. 5.3.2 .

At FAL3, the RP is also responsible for verifying the presentation of the bound authenticator, as discussed in [SP800-63C] . The bound authenticator could also be a PIV credential, but it is not necessary for it to be one (see Sec. 4.1.3 for more information about bound authenticators).
