Abstract

A method of guaranteeing users' anonymity and a wireless LAN system therefor are provided. In a wireless LAN system, the method of guaranteeing user' anonymity includes (a) creating a plurality of temporary address sets, each of which corresponds to a unique Media Access Control (MAC) address of a wireless terminal and transmitting the temporary address set to the corresponding wireless terminal, and (b) performing data packet transmission between the wireless terminal and the wireless access node using a temporary address selected from the temporary address set as a source address or a destination address. Therefore, it is possible to guarantee users' anonymity and improve security of a system by not exposing a MAC address during data packet transmission between a wireless terminal and a wireless access node.

Description

technical field [0001] The present invention relates to wireless local area network (LAN) systems. More particularly, the present invention relates to a method of securing user anonymity and a wireless local area network system thereof using a temporary address generated from a unique Media Access Control (MAC) address as a source address or a destination address. Background technique [0002] Generally, a wireless local area network (LAN) system includes: an ad-hoc network in which multiple terminals are connected to each other and independently connected to a wired LAN, each terminal including a wireless network interface card (NIC); and a base network, in which wireless terminals are connected to wired LANs through wireless access nodes. In the basic network, with a wireless access node as the center, a wireless unit basic service equipment (Basic Service Set, BBS) is formed. The wireless access node has the same function as the cell phone station, and connects all the ...
