Problems solved by technology

The problem is: NAF2 does not know AUTN and RAND at this time, so it is actually impossible for NAF2 to send AUTN and RAND to UE
Since the above-mentioned process of obtaining Ks is time-consuming, it ultimately affects the performance of the UE

Embodiment Construction

[0080] In the case where multiple NAFs (Network Application Functions) implement GBA PUSH with the same UE (User Equipment), when the UE successfully implements network-side authentication with the first NAF and implements GBA PUSH, the UE will save its connection with the first NAF. A NAF implements the basic key Ks information obtained during the GBA PUSH process, such as the correspondence between Ks and B-TID stored by the UE. In this way, when the UE successfully completes the network side authentication in the subsequent GBA PUSH process of NAF, the UE in the present invention can make full use of the feature of storing Ks information in the GBA PUSH implementation process to find the Ks corresponding to the subsequent session guidance process. , so that the UE can directly use its stored Ks information to calculate the derived key Ks_NAF, and use the derived key to realize the decryption process of the PUSH data sent by the above-mentioned other NAFs, avoiding the UE from ...

Abstract

The invention provides s method, equipment and system which can realize pushing function based on common-use guiding framework, UE in the invention checks basic key corresponding with guiding dialogue course between said BSF, after attestation of network side is successful, based on basic key, course of data deciphering can be realized. The BSF of the invention obtains attestation information of UE and network side, and returns the attestation information obtained to any NAF which needs pushing to UE without condition, NAF which receives the attestation information sends the attestation information to UE when it judges that UE does not possess guiding dialogue course, UE accomplishes course of network attestation and data deciphering; so, when several NAFs and the same UE realize GBA PUSH, course of UE calculating basic key for every NAF can be avoided, performance of UE is increased, and, problem that UE can not realize network side attestation is also avoided; so pushing function can be improved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method, device and system for realizing a push function based on a general guidance framework. Background technique [0002] The GBA (Generic Bootstrapping Architecture, general bootstrapping architecture) defined in 3GPP (The Third Generation Partnership Project, third generation mobile communication system) is attached figure 1 shown. [0003] figure 1 Among them, the general authentication framework is usually composed of IMS users namely UE, BSF (Boot Service Function Entity), HSS (User Home Server), SLF (Subscriber Location Function Entity) and NAF (Network Service Application Entity). The BSF is used for mutual identity verification when performing a bootstrapping process (bootstrapping) with the UE, and at the same time generates a shared key Ks between the BSF and the user. The HSS stores the subscription file used to describe user information, and the ...
