"Relying Party" is a generic term used in multiple contexts. As I
understand it, a 'Relying Party' is an application or service that
consumes authorization or authentication assertions and checks their
validity using a trusted third party.

(In context of the RPKI, these trusted third parties are represented by
self-signed X.509 root certificates, so-called "Trust Anchors".)

The phrase 'RP' is used in the RPKI (which is based on X.509), and
the broader X.509 community, and indeed also in communities around
technology like OAUTH 2.0.

The RPKI community has been using the phrase "Relying Party (RP)" in
dozens of RFCs for nearly two decades.

As far as I know there are no places where OAuth 2.0 and the RPKI
interact.

I don't think now is the moment or this is the document to suddenly
start explaining that OAUTH also uses the phrase 'RP'. :-)

Kind regards,

Job
