[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0027] Figure 1 is a schematic diagram of the WAPI application structure in a wireless mesh network. Several adjacent physical APs in the wireless mesh network are virtualized as the same virtual AP, and the same virtual AP certificate is installed in these physical APs (the distribution, management and installation of the certificate are not within the scope of the present invention). Connecting an STA to any physical AP in the network is equivalent to connecting to this virtual AP, and the connected physical AP implements the function of a virtual AP.
[0028] Figure 2 is the authentication flow chart of the STA connecting to the wireless mesh network for the first time. The STA connects to the wireless mesh network for the first time, and the WAPI authentication process based on the virtual AP is as follows:
[0029] Step 1: The virtual AP sends an authenticat...
