Abstract: Providing 5G-AKA User Equipment (UE) authentication and, more specifically, providing 5G-AKA UE authentication at an edge of a network may be provided. An Authentication Server Function (AUSF) at an edge of a network, and the AUSF may request an Authentication Vector (AV) from a Unified Data Management (UDM). The AUSF may receive AV from the UDM and cache the AV at an AV cache. An authentication request may be received from an Access and Mobility Management Function (AMF) and the AV from the AV cache may be provided to the AMF.

Abstract: Generic bootstrapping architecture (GBA) based procedures over Constrained Application Protocol (CoAP) for use in authenticating and/or securing communications with Internet of Things (IoT) devices are provided. In one illustrative example, the device sends to a bootstrapping server function (BSF) a first CoAP request carried in a Confirmable (CON) message, where the first CoAP request indicates a request for initiating a bootstrapping procedure. In response, the device receives from the BSF a first CoAP response carried in an Acknowledgement (ACK) message, where the first CoAP response indicates an authentication challenge. The device sends to the BSF a second CoAP request carried in a CON message, where the second CoAP request includes a challenge response to the authentication challenge. The device receives from the BSF a second CoAP response carried in an ACK message, where the second CoAP response includes a bootstrapping transaction identifier (B-TID) which indicates a successful authentication. The device generates a bootstrapping session key (Ks) and stores it in association with the B-TID. An HTTP messaging-based server (e.g. BSF or NAF) may utilize a module, such as a plug-in module, for message translation between CoAP and HTTP.
