Embodiment Construction

[0063] The following is a detailed description of the method of the present invention in conjunction with the flow chart 4 of compatible scheme execution and the protocol interaction process 5 of executing WAPI:

[0064] 1. The mobile station STA sends an EAP start message EAPOL-Start to the access point AP.

[0065] This message indicates that the mobile station STA requests EAP identity authentication, and its specific message format adopts the definition of EAPOL-Start in 802.11i.

[0066] 2. The access point AP sends a timestamp request message EAP-Req / WTS to the mobile station STA.

[0067] Through the time stamp request message EAP-Req / WTS, the access point AP requests the mobile station STA to send its identity and current access time. Since there is no such message type in the current EAP message, a new message type type: WAPI-WTS needs to be added to the EAP message. The format of this message is shown in Figure 6.

[0068] The message format shown in Fig. 6 is def...

Abstract

The invention discloses one method combined with 802.11i and WAPI identification, which comprises the following steps: mobile station STA to interface point AP extensive certificate agreement EAP initial information and the AP sending STA to time stamp information; if the STA supports WAPI to AP for answer information and sending identification and interface require time for signature; if the ASU supports WAPI then processing codes negotiating and sending AP to key transmission information; if the STA or WAPI not supporting identification then processing 802.11i; finally processing hand holding agreement by STA and AP.

Description

technical field [0001] The present invention belongs to the technical field of wireless communication, and relates to the security technology of wireless local area network, and specifically aims at the problem that the international wireless local area network security standard 802.11i is not compatible with the Chinese wireless local area network security standard WAPI, and proposes an authentication scheme compatible with both, To solve the identity authentication and key negotiation problems when foreign wireless products enter the Chinese market. Background technique [0002] With the rapid development and popularization of wireless local area network (WLAN), its security issues have aroused more and more people's attention. The IEEE802.11 working group is committed to formulating a new generation of security standards called 802.11i. This security standard enhances the data encryption and authentication performance of WLAN, and has made many improvements to the defects...
