Which if the following is NOT one of the three components of a federated identity system transaction?

The Relying Party (RP) is a crucial component that relies on the identity assertion from the IdP to grant access to a resource or service.

The Identity Provider (IdP) is essential as it is responsible for authenticating the user and providing identity information to the Relying Party.

The User is the entity attempting to access resources and initiating the authentication flow across the federated system.

The three core components of a federated identity system transaction are the Identity Provider (IdP), which authenticates the user and asserts their identity; the Relying Party (RP), which trusts the IdP and grants access to resources based on the assertion; and the User, who requests access to the RP's resources. A proxy relay is not a standard, foundational component of this direct trust model.
