Abstract
A method for mitigating network function (NF) update and deregister attacks includes, at an NF repository function (NRF) implemented by at least one processor, receiving, from an NF, an NFRegister request including a hash of a first authentication string, an NF instance identifier, and an NF profile. The method further includes storing the hash of the first authentication string. The method further includes registering the NF by storing the NF profile in an NF profile database. The method further includes receiving a first NFUpdate or NFDeregister request including the NF instance identifier. The method further includes using the stored hash of the first authentication string to validate or reject the first NFUpdate or NFDeregister request.
