[0063] The following is a detailed description of the method of the present invention in combination with the flowchart 4 executed by the compatible solution 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 time stamp 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 the current EAP message does not have this message type, a new message type type: WAPI-WTS needs to be added to the EAP message. The format of the message is shown in Figure 6.
[0068] The message format shown in Figure 6 is defin...
