Problems solved by technology

However, as the virtual operator concept becomes more widely used for hotspot WLAN access, the problem of identifying authenticated sessions without relying solely on the source IP address becomes more pressing, as the potential for hackers to gain access to the computer will scale accordingly. rise

Embodiment Construction

[0018] In the figures to be discussed, circuits and associated blocks and arrows represent functions according to the method of the invention, which may be implemented as circuits and associated wiring or data buses for the transmission of electrical signals. Alternatively, one or more connected arrows may represent communication (eg, data flow) between software programs, particularly when the methods or apparatus of the present application are implemented as digital processes.

[0019] According to FIG. 1 , usually for the purpose of accessing secure databases or other sources requiring high security from unauthenticated entities (such as hackers), by 140 1 to 140 n represented by one or more mobile terminals via access point 130 1 to 130 n And the associated computer 120 communicates with the verification server 150 .

[0020] As further illustrated in Figure 1, the IEEE 802.1x architecture consists of several components and services that interact to provide station mobil...

Abstract

A method for improving the security of a mobile terminal in a WLAN (124) environment by redirecting the browser request, embedding a session identification (session ID) inside an HTTP request and matching two HTTP sessions using such a session ID in the authentication server (150). The access point (130) processes the web request from the mobile terminal such that a session ID becomes embedded in the universal resource locator (URL). Additionally a mapping between this session ID and the MAC address or the IP address of the mobile terminal is maintained in the WLAN. When the authentication server notifies the access point about the authentication result, the session ID is used to uniquely identify the mobile terminal. All these operations are transparent to the mobile terminal (140).

Description

[0001] This application claims the benefit of US Provisional Patent Application Serial No. 60 / 453,329, filed March 10, 2003, which is hereby incorporated by reference. technical field [0002] The present invention provides an apparatus and method for improving wireless local area network ("WLAN") security and Access control. Background technique [0003] The context of the present invention is the wireless local area network or (WLAN) family utilizing the IEEE 802.1x architecture with access points (APs) for providing mobile devices with access to other wireless local area networks such as hardwired local area networks. Network and access to the global web such as the Internet. Advances in WLAN technology have resulted in publicly accessible hotspots at restrooms, cafes, libraries and similar public facilities. Currently, public WLANs provide mobile communication device users with access to private data networks, such as corporate intranets, or public data networks, such ...
