X.509 Certificate Extended Key Usage for 5G Network Functions
RFC 9509, “X.509 Certificate Extended Key Usage for 5G Network Functions”, is a Proposed Standard document published in March 2024 by T. Reddy.K, J. Ekman, D. Migault. The canonical text is published by the RFC Editor.
Abstract
RFC 5280 specifies several extended key purpose identifiers (KeyPurposeIds) for X.509 certificates. This document defines encrypting JSON objects in HTTP messages, using JSON Web Tokens (JWTs), and signing the OAuth 2.0 access tokens KeyPurposeIds for inclusion in the Extended Key Usage (EKU) extension of X.509 v3 public key certificates used by Network Functions (NFs) for the 5G System.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
