| Summary: | In order to solve the problems of 5G network handover authentication and key update mechanism， such as lacking of forward security， being vulnerable to bypass attack and having signaling congestion， for 5G enhanced （B5G） network， an efficient handover authentication and security key-updating mechanism based on no certificate was proposed.The certificateless key agreement mechanism was introduced in the network edge side， which made the mobile terminals in-itiate the key-updating request actively and complete the whole certificateless key-updating process on the fly.The security of the key-updating mechanism was proved theoretically based on the Diffie-Hellman problem under the eCK security model.Simulation results demonstrate that the proposed mechanism not only meets the forward security of mobile terminal key management， but also has lower communication and computing overheads compared with other similar handoff authentication. |
