4G/5G Application Authentication and Authorization

4G/5G NFs use mTLS to secure communication. All NFs require a trust relationship to be established with all peers (by exchanging and trusting peer root or intermediate certificates). All the peer certificates must be available in the trust store (K8s Secrets) in order to establish secured communication. Ideally, the trust store is populated from the customer PKI using ACME protocols; we also support manual importation and a semi-automatic import using the cert-manager external provider.
