In an identity verification method for a network function service, a network element receives from a requesting network element a network function (NF) service request that includes a token, The token includes first certificate information. The network element verifies the first certificate information to determine whether an identity represented by the first certificate information is consistent with an identity of the requesting network element. When the network element determines that the identity represented by the first certificate information is inconsistent with the identity of the requesting network element, the network element rejects the NF service request.
