Abstract
A method for protecting against unauthorized use of CMP client identity private keys and CMP public key certificates associated with NFs includes receiving, by a CMP CA proxy, a first CMP certificate request for renewing a security certificate associated with a first NF, the CMP certificate request including a public key certificate associated with the first NF and is protected by a CMP client identity private key associated with the first NF. The method further includes determining that the first NF is registered with the NRF, and, in response to determining that the first NF is registered with the NRF, checking, by the CMP CA proxy whether the first CMP certificate request includes an NRF-issued access token for the first NF, determining that the CMP certificate request does not include the NRF-issued access token for the first NF, and, in response to determining that the first CMP certificate request does not include the NRF-issued access token for the first NF, performing a network security action regarding the first CMP certificate request.
