UAAF produces the management authentication credential between CNG and CNGCF, and sends the management authentication credential to CNGCF. CNG obtains the management authentication credential. CNG authenticates CNGCF by the obtained management authentication credential and CNGCF authenticates CNG by the management authentication credential. A system for management authentication based on NASS is also disclosed. The authentication credential can be automatically produced, distributed and modified. And the operation cost is reduced and the operation efficiency is enhanced.
