Broadcast encryption is an important method to implement content access control in Named Data Networking. Through Broadcast encryption, content can be safely shared within network. However, existing Random Grouping Strategy result in increased redundancy of content replicas in the network. which seriously restricts network performance. In view of this, a User Location Grouping based Broadcast Encryption Access Control in NDN (ULBBE-AC)is proposed in this paper. By modifying the interest packet structure, a TraceRouteTag field is added to the interest packet, which is used to determine the user’s relative position in the network topology. In ULBBE-AC, the users in the same area will be divided into the same group as much as possible and broadcast encryption-based access control is performed for different groups, which improves cache utilization. The simulation results of ndnSIM show that compared with Radom Group Broadcast Encryption-Access Control, ULBBE-AC improves cache utilization and reduces the time cost of content acquisition.
