The authentication process based on 5G authentication and key agreement in 5G system is analyzed, together with the characteristics of 5G AKA authentication mechanism, the specific design of 5G AKA authentication process is completed in terminal, including process design and interface design. The SDL function diagram is constructed on the SDL and TTCN-3 co-simulation platform, and the 5G AKA authentication process is tested. The test results are analyzed to check the consistency of 5G AKA authentication process with the standard. %U http://cea.ceaj.org/EN/10.3778/j.issn.1002-8331.1901-0115
