Abstract
It is possible to reduce singling overhead in a radio access network by coordinating authentication of a group of UEs (e.g., IoT devices, etc.) via a master device. In particular, the master device may aggregate UE identifiers (UE_IDs) for UEs in the group, and send an identity message carrying the UE_IDs and a master device identifier (MD_ID) to a base station, which may then relay the identity message to a Security Anchor Node (SeAN). The SeAN may send an authentication data request carrying the UE_IDs and MD_ID to a Home Subscriber Server (HSS), which may return an authentication data response that includes a group authentication information. The group authentication information may then be used to achieve mutual authentication between the SeAN and each of the master device, group of UEs, and individual UEs.
