Methods, systems, and computer readable media for automatically binding a service-based interface (SBI) communications digital certificate lifecycle to a network function (NF) lifecycle

Abstract

A method for automatically binding an SBI communications digital certificate lifecycle to an NF lifecycle includes receiving, at an NRF, an NF deregister request message for deregistering an NF. The method further includes generating, by the NRF and in response to the NF deregister request message or successful completion of deregistration of the NF, a certificate revocation request message for revoking at least one digital certificate used by NF for SBI communications. The method further includes transmitting, by the NRF, the certificate revocation request message to a certificate authority. The method further includes receiving, by the NRF, an NF register request message identifying the NF. The method further includes determining, by the NRF, that the at least one digital certificate of the NF has been revoked. The method further includes, in response to determining that the at least one digital certificate of the NF has been revoked, performing, by the NRF, a network security action in response to the NF register request message.
