Abstract: In order to solve the problems of poor anonymity, complex authentication process and low generality of handover protocol between network slices, an efficient universal secure handover authentication and key negotiation protocol based on no certificate is proposed. The key negotiation protocol based on certificateless mechanism can solve the problems of certificate storage and key management in traditional public key infrastructure, and can effectively improve the efficiency of handover authentication under the premise of ensuring security. The proposed agreement achieves privacy protection for users and network slices by introducing user pseudo-identities and slice identity identifier. For network slicing of different service types, an edge controller is introduced between the user and the slicing service provider to assist the inter-slice handover process to ensure that legal users can achieve fast and universal identity authentication during the handover process. Simulation results show that the proposed protocol can improve the efficiency of inter-chip handover authentication and realize a secure and universal handover process.
