ABSTRACT:
The secure wireless local area network of the present invention includes a single wired network that supports both wired and wireless devices. The network addresses security concerns by including an authentication server that services a plurality of access points. Each access point includes a first authentication device that generates and transmits a first authentication message to the corresponding wireless device over an air channel. The first authentication message includes encrypted validating information about the access point including an access point key that uniquely identifies the access point. Each wireless device includes a second authentication device. The wireless device receives the first authentication message and determines whether the access point is authorized to connect to the wired network. If the access point is valid, the second authentication device responds to the first authentication message by generating and transmitting a second authentication message to the access point. The second authentication message includes encrypted validating information about the wireless device and operator, e.g., a device key and the operator's logon name and password. The access point determines the authenticity of the wireless device by decrypting the portion of the second authentication message that includes the device key. If the wireless device is valid, the AP opens a control channel with the authentication server. The AP transmits the first and second authentication messages to the authentication server. If the authentication server validates the access point and the operator's logon name and password, it will authorize access to the wired network.
