To solve the problem of switching delay caused by repeated identity authentication during net-work slicing scene switching,a network slicing scene switching algorithm based on directed acyclic graph(DAG)authentication is proposed.Firstly,the algorithm implements the continuous identity authentication of user scene switching from the aspect of DAG authentication to ensure that the user can quickly realize the network slicing scene switching.Then,to solve the problem of multi-user scene switching,the conditional generation adversarial network algorithm under Wassertein optimization is used to determine the priority of scene switching,which ensures the low drop rate of user scene switching.Simulation results show that the proposed algorithm achieves lower handover delay by avoiding additional authentication,and improves drop rate performance under low delay..
