摘要
PURPOSE: A wireless LAN system and method for securing a user's anonymity is provided to guarantee a user's anonymity by using a tentative address, randomly selected from a tentative address set created correspondingly with an intrinsic MAC address, as a source address or a destination address when data packets are transmitted between a wireless access node and a wireless terminal. CONSTITUTION: In case that the first wireless terminal makes an association request, the association between the first wireless terminal and a wireless access node is performed(21). If the first wireless terminal transmits an authentication request message, including its own intrinsic MAC address, to the wireless access node, the wireless access node executes the authentication of the first wireless terminal. If the authentication is successful, the wireless access node creates an encryption key(22). The wireless access node randomly converts the intrinsic MAC address and creates a tentative address set composed of Numbers of tentative addresses corresponding to the intrinsic MAC address(23). The wireless access node encrypts the tentative address set using the encryption key and transmits it to the first wireless terminal(24). In every data communication between the wireless access node and the first wireless terminal, a tentative address to be used as a source address or a destination address is randomly selected from the tentative address set and data packets are transmitted(25).
