<P>PROBLEM TO BE SOLVED: To provide a security model for wireless LAN that can support sharing of a single physical BSS, without introducing vulnerabilities or compromising security among stations. <P>SOLUTION: The security model for the wireless LAN instantiates a Personal VLAN bridge using IEEE Std. 802.11 elements. The result is a bridge, referred to as a public access point PAP, that is better suited for implementing public wireless data networks than the IEEE Std. 802.11 architecture. The invention also provides a location-update protocol for updating the forwarding tables of bridges that connect public access points together. The invention further provides a method for more controlled bridging, which is referred to as fine bridging. <P>COPYRIGHT: (C)2010,JPO&INPIT |
