Embodiment Construction

[0035] The Generic Bootstrapping Architecture (GBA), defined in 3GPP Technical Specification TS 33.220, provides mechanisms by which a client terminal (UE) can be authenticated to a network application function (NAF), and a secure session key is obtained for use between the UE and the NAF . like figure 2 As shown, GBA provides the following mechanism: UE uses Bootstrap Server Function (BSF) to perform bootstrapping to authenticate UE to BSF, and obtain master key Ks and bootstrap transaction identifier (B-TID). During bootstrapping, the BSF obtains the GBA User Security Settings (GUSS) from the Home Subscriber System (HSS). Then the UE derives the application-specific key Ks-NAF based on Ks and the NAF identifier NAF_ID, where NAF_ID is constructed as the concatenation of the fully qualified domain name (FQDN) of the NAF and the security protocol identifier of the reference point Ua, where the connection between the UE and the NAF The communication between is via said refer...

Abstract

A method is provided for authorizing a subscriber user equipment to access a network application function (NAF) in a general bootstrapping architecture (GBA). The method comprises: receiving, at a Bootstrap Server Function, BSF, a request for keying material for a subscriber User Equipment from a NAF, wherein the NAF is associated with one or more NAF identifiers NAF_ID; obtaining subscriber information from a Home Subscriber System, HSS, Said information includes one or more NAF_IDs valid for the subscriber; authorizing the subscriber user equipment according to the identification of said NAF and the NAF_ID included in the subscriber information. In the case of authorized subscriber user equipment, deriving keying material using the NAF_ID contained in said subscriber information; and sending said keying material to said NAF.

Description

technical field [0001] The present invention relates to methods and apparatus used in a generic bootstrap architecture. More specifically, the present invention relates to methods and apparatus for authorizing subscriber user equipment. Background technique [0002] To facilitate provisioning of services to user terminals, mobile networks such as 3G networks typically require the establishment of a secure communication channel or "security association" between a client terminal (eg, mobile terminal) and a network-based service node providing the service. The Generic Bootstrapping Architecture (GBA) defined in 3GPP Technical Specification TS 33.220V11.1.0 (2011-12) provides a mechanism that can authenticate a client terminal (UE) to a network application function (NAF) (ie, an application server) The secure session key obtained for use between the client terminal and the NAF. figure 1 Schematically shows an example of a simple network model of GBA as described in 3GPP TS33....
