Embodiment 1

[0029] Such as figure 2 As shown, it is a schematic structural diagram of a network access authentication device according to an embodiment of the present invention. The network access authentication device 20 includes: a message receiving unit 201 for receiving an authentication request message sent by an access point; Or the network access authentication device obtains the security key generated through the authentication between the access point and the authentication server; the tunnel establishment unit 203 is configured to establish a secure tunnel with the access point according to the security key.

[0030] Optionally, the authentication request message sent by the access point may include an XAP authentication message. Such as image 3 As shown, it is an embodiment of the present invention figure 2 Schematic diagram of the structure of the tunnel establishment unit in . The tunnel establishment unit 203 may include: a calculation module 2031, configured to calcul...

Embodiment 2

[0041] The aforementioned access point may be a FAP, the network access authentication device may be a security gateway, and the authentication server may be a FAP authorization, verification and accounting server. The application examples are given below to illustrate. It is worth mentioning that it is not limited thereto, and this technical solution can be used not only in the Femtocell system, but also in other systems where redirection of network access authentication devices occurs.

[0042] Such as Figure 7 As shown, it is a network architecture diagram of network access authentication device redirection as an application example of the present invention. The following embodiments of the present invention are intended to solve the problem after SeGW (security gateway) redirection (from SeGW1 (authentication device 1) 702 to SeGW2 ( The authentication device 2) 704) authorizes the authentication of the FAP701, that is, the EAP authentication when the location of the aut...

Abstract

The invention provides a networking authentication method and a device, wherein the method is used after the networking authentication device of an access point is orientated again. The method comprises the following steps: receiving an authentication request message sent by the access point; obtaining an authentication generated safe key between the access point and a authentication server through the networking authentication device from the authentication server or the networking authentication device; and establishing safe channels according to the safe key and the access point. The embedment of the invention provides the networking authentication device. In the technical scheme, because the networking authentication device adopts the technical measures of establishing the safe channel with the access point by the request access point through the safe key authenticated and generated by a default gateway and the authentication server according to the fed back safe key, the invention solves the problem of how to authenticate the access point after the networking authentication device is orientated again.

Description

technical field [0001] The invention relates to the field of network access authentication, in particular to a network access authentication method and device. Background technique [0002] Femto Cell (super mini base station) is a system composed of Femto Access Points (Femto Access Point, FAP) and other network entities that provide necessary functions for users to access wireless networks through FAPs. Such as figure 1 As shown, it is a prior art Femto Cell network architecture diagram, which includes: [0003] The FAP 101 is a low-power Worldwide Interoperability for Microwave Access (WIMAX) base station (BS). This BS provides small-scale wireless coverage and is mainly used indoors, such as SOHO (separate office, home office) environment. It uses a wired broadband network, such as digital subscriber line / IP (DSL / IP) network access, where the wired broadband network may belong to different operators from the WIMAX network. [0004] Security Gateway (SeGW) 102, locate...
