Further, if the device assumes a false identity, NAF may issue GPI in vain (Ks_NAF will never be successfully received and recovered and may leave NAF hanging with a crashed security association)

Embodiment Construction

[0075] The Ub interface of the GBA allows messages or communications to be sent between one or more UEs 20 and the BSF 30 (see figure 1 ). The Ub interface is replaced by a proxy 110, an intermediary or a proxy server. In one embodiment, the agent 110 is placed on the same server platform hosting the NAF 40 . For example, this could be a device management (DM) server 50 platform. Proxy 110 addresses security issues for direct connections between UE 20 and BSF 30 . Proxies can filter and inspect the Ub protocol to ensure that message delivery is well formed and consistent with GBA standards before passing the message to the BSF. It also helps in cases where UEs do not support the HTTP stack, as the proxy can perform protocol translation if necessary. exist figure 2 This modified flow (including agent 110) is shown in . In particular, processes involving agent 110 are circled 100 .

Abstract

The invention relates to a generic bootstrapping architecture protocol. Method and system for communicating securely with a user equipment, UE, using generic bootstrapping architecture, GBA, the system comprising a bootstrapping server function, BSF. A proxy server configured to receive messages from a user equipment, UE, in a first format. Convert the received messages from the first format to a second format. Transmit the received UE messages to a bootstrapping server function, BSF, in the second format. Receive messages from the BSF, in a third format. Convert the messages received from the BSF from the third format to a fourth format. Transmit the received BSF messages to the UE in the fourth format.

Description

technical field [0001] The present invention relates to a system and method for establishing secure communication with a UE using a GBA. Background technique [0002] Generic bootstrapping architecture (GBA) enables authentication of users for specific services. GBA uses several different elements, which include User Equipment (UE), Application Servers or Network Application Functions (NAFs) that provide specific services, Bootstrap Server Functions (BSFs) and the mobile operator's Home Subscriber Server (HSS) or Home Location Register (HLR). exist figure 1 These elements are shown in system 10. GBA is a well-established standard employing a defined interface (Ub) between the UE and the network-based BSF. exist figure 1 The interface flows involving Ub are shown with circles in . [0003] However, this Ub flow presents several difficulties. First, there are several backward and forward messages (four in case of success and even more in case of unsuccessful or error), ...
