name: RP
full_form: Relaying Party
context: UE authentication. This allows to stop the protocol in the case of a failed RP authentication, and saves communication effort between UE and OP in the case of such a failed RP authentication. The OP can then directly convey the information on the failed RP authentication to the UE. Using Associations for RP authentication If the RP establishes an association with the OP, the OpenID association protocol can be slightly modified to incorporate a challenge from the OP to be conveyed to the RP for the purpose of RP authentication. During the association establishment the OP and RP can set up a message authentication code (MAC) key which is later used to sign the assertion message. This key is sent encrypted using a temporary secret key which is negotiated between OP and RP using Diffie-Hellman (DH). In addition to that key, deviating from the OpenID specs, the OP can include a nonce, also encrypted with the DH-key, in the response to the RP. The RP can then decrypt the nonce and the MAC
description: The Relaying Party (RP) is an entity that plays a crucial role in the authentication process between the User Equipment (UE) and the OpenID Provider (OP). It acts as an intermediary, facilitating communication and authentication between the UE and OP. The RP establishes associations with the OP, uses message authentication codes (MAC), and handles encryption and decryption of sensitive information.
explanation: The context describes the RP's involvement in authentication, association establishment, and secure communication handling, indicating its active participation in network operations and interactions between entities, which defines it as a Network Function.
