Abstract
Various aspects of the present disclosure relate to authenticating user equipment (UE) for applications. A first communication device (e.g., a network entity, a server device) authenticates a second communication device (e.g., a UE) for authentication and key management for applications (AKMA) with a challenge, such as an authentication vector (AV), computed based on the AKMA anchor key (K) corresponding to the second communication device. Comparison of the challenge result (RES) received from the second communication device and an expected challenge result (XRES) is performed by an AKMA anchor function (AAnF) or by an application function (AF), and the AKMA application key (K) for the AF is only provisioned after the comparison indicates a successful communication device authentication (e.g., the RES and the XRES are the same).
