Original Abstract Submitted
Systems and methods for Generic Bootstrapping Authentication (GBA) are disclosed herein. A method performed by a User Equipment (UE) for GBA may include: communicating, at a GBA application, with a network node to run a GBA procedure during which the GBA application obtains a key, Ks, and a Bootstrapping Transaction Identifier (B-TID); providing to the GBA application, at an application, an application key request, the request including a Network Application Function (NAF) identifier; at the GBA application: verifying that the application is entitled to use a NAF corresponding to the NAF identifier; and responsive to successful verification: deriving the application key for the application based on the key, Ks, the NAF identifier, and an additional parameter generated by the GBA application or an application identifier; and sending a response to the application; and receiving, at the application, the response from the GBA application.
