name: GUSS
full_form: GBA User Security Settings
context: subscriber profile data may be fetched by the NAF from its local database. NOTE 2: One possibility to revoke temporarily an application specific USS from the GUSS is that the HSS may temporarily remove an application-specific USS from the GUSS if the service is temporarily revoked from the subscriber. The GUSS in the BSF is not changed by this operation and only updated when the existing bootstrapping session times out, or is overwritten by a new bootstrapping session during which the new modified GUSS is fetched from HSS along with the AV. - GUSS shall be able to contain parameters intended for the BSF usage: - subscriber specific key lifetime; - optionally the timestamp indicating the time when the GUSS has been last modified by the HSS. NOTE 3: These parameters are optional and if they are missing from subscriber's GUSS or subscriber does not have GUSS then the BSF will use the default values in the BSF local policy defined by the particular MNO. - HSS shall be able to assign
description: The Bootstrapping Server Function (BSF) is a network function that plays a crucial role in the bootstrapping process of the Generic Bootstrapping Architecture (GBA). It interacts with the Home Subscriber Server (HSS) to fetch and update the GBA User Security Settings (GUSS), which contain parameters such as subscriber-specific key lifetime and timestamp indicating the last modification time by the HSS.
explanation: The context describes the BSF's responsibilities in managing GUSS within the GBA framework. Its interaction with the HSS and role in updating security settings clearly define it as a network function.
