The master access device 20 includes a message receiving module 21 and a checking module 22, where the message receiving module is configured to receive an Association Request message (Association Request message), and the checking module is configured to check whether a WDS authentication identifier in the WDS authentication information (Vendor Specific IE) exists in the Association Request message (Association Request message);
the primary access device 20 further includes an obtaining module 23, configured to obtain, when a WDS authentication identifier in the WDS authentication information (vector Specific IE) exists in the Association Request message (Association Request message), a user account and an account password in the WDS authentication information (vector Specific IE) from the Association Request message (Association Request message);
and the authentication module 40 is configured to authenticate the user account and the account password.
The association module 50 is configured to, when the user account and the account password are successfully authenticated, associate the secondary access device 10 with the primary access device 20, and then enable the secondary access device 10 to access an external network;
the Association module 50 is configured to, when a WDS authentication identifier in the WDS authentication information (Vendor Specific IE) does not exist in the Association Request message (Association Request message), or when authentication of the user account and the account password fails, associate the secondary access device 10 with the primary access device 20, and then the secondary access device 10 cannot access the external network.
Specifically, the secondary access device may be a secondary router, and the primary access device may be a primary router; when the main router acts as a fat AP (wireless access point), setting a corresponding user account and account password on the main router, and authenticating on the main router, wherein the authentication module 40 is arranged on the main router; when the main router acts as a thin AP (wireless access point), a corresponding user account and account password are set on the wireless controller (AC), and authentication is performed on the wireless controller (AC), and the authentication module 40 is set on the wireless controller (AC).
According to still another embodiment of the present invention, a WDS authentication method includes the steps of: adding a Vendor Specific IE into an Association Request message sent by a secondary router, wherein the content of the Vendor Specific IE comprises: WDS authentication identification, user account and user password.
After receiving the authentication Request, the main router checks the Vendor Specific IE, finds a WDS authentication identifier, shows that the Vendor Specific IE is used for WDS authentication, then obtains a user account and a password for authentication, and if the authentication passes, the auxiliary router does not need to perform Portal authentication and directly allows the auxiliary router to access the external network after association. Certainly, there is a security problem in directly transmitting the account number and the password of the plaintext through the Vendor Specific IE, and the WIFI mode may be encrypted through 802.11w or other modes.
Generally, a master router opens Portal authentication, when a client STA accesses the master router, the client STA firstly associates the master router, and under the Portal authentication, the SSID of the master router is generally configured to be Open, so that association must be successful but the external network cannot be accessed, and the Internet access can be realized only after Portal succeeds.
The process is also adopted when the auxiliary router is associated with the main router, but the auxiliary router cannot initiate Portal authentication, and no interface inputs a user name and a password, so that the auxiliary router cannot normally access the external network.
It should be noted that the above embodiments can be freely combined as necessary. The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
