Abstract
A method for a user equipment (UE) configured to communicate with an application function (AF) via a communication network is provided. The method comprises sending, to the AF, an application service request including: a second identifier (GPSI) specific to one or more applications, including an application associated with the UE and the AF; and information (app-info) associated with the second identifier and descriptive of the one or more applications. The method further comprises authenticating the AF based on an application-specific key (KAF) derived from a security key (KAKMA) associated with the UE; and receiving, from the AF, an application service response indicating whether the second identifier (GPSI) matches a corresponding second identifier (GPSI*) derived from the information associated with the second identifier.
