Problems solved by technology

[0071] 7. Insufficiency of the current WAPI design
For example, individual users may want to use the method of manually entering the key for authentication, while mobile communication operators have been accustomed to using SIM (Subseriber Identification Module) cards for a long time to identify mobile phone users; if digital certificates are to be used, individual users need to purchase and To maintain an authentication server, mobile communication operators must establish and maintain an additional authentication mechanism, which will greatly increase costs and affect economic benefits

Embodiment Construction

[0141] Talk about several embodiments of the present invention below in conjunction with drawing.

[0142] This method defines the Figure 5 As shown, the state machine of the mobile terminal MT5 when performing protocol negotiation with the access point AP5. The leading idea of ​​this state machine is that unless MT5 only supports the original WAPI and does not support the extension described in the present invention at all, otherwise MT5 always proposes the party selected by the agreement first; this is manifested in the condition that MT5 does not receive the information of AP5 The next server actively sends protocol negotiation information according to its NAP table variable value.

[0143]Although MT5 sends a protocol selection message, it cannot be fully expected that AP5 will respond to its message. First of all, the information sent and answered may be lost; moreover, AP5 may only support the original WAPI and does not support the method of the present invention at a...

Abstract

A method for adding other authentication protocol in IEEE802.11 WAPI (WLAN Authentication and Privacy Infrastructure), especially adding the authentication protocol based on key shared by access point and mobile terminal, and based on EAP (Extensible Authentication Protocol), said method realizes adding new protocol in original WAPI and selecting between original WAPI and new added protocol, permitting the mutual authentication between the access point with / without new added protocol and mobile terminal, insuring compatible with original WAPI protocol, said invention can escalate access point with WAPI and mobile terminal, in authentication, both of original WAPI and new added protocol can be set forced use, and also can set use access point and terminal neachievediation protocol, in all supporting new added protocol using WAPI or new added protocol, in one part does not support new added protocol using original WAPI.

Description

technical field [0001] The present invention relates to a method for realizing a peer-to-peer wireless local area network authenticated by a center, in particular to an IEEE802. 11 and IEEE802.11i wireless local area network protocol) protocol support function, the method of completing authentication and connection between client sites through the help of access point and authentication server belongs to the field of wireless communication technology and Internet technology. Background technique [0002] 1. Wireless LAN [0003] The wireless local area network (WLAN or Wireless Local Area Network) here refers to a wireless network based on the IEEE802.11 protocol series. Wireless local area network transmits data through wireless signals, getting rid of the limitation of wires. The wireless local area network (infrastructure, that is, the infrastructure mode) uses the access point AP (Access Point) as the central station to cover a certain area, and wirelessly connects and...
