Robust Secured Roaming in Wireless Local Area Networks

摘要

This article describes how wireless local area networks are the prime way of accessing the internet nowadays. A secure roaming of information between the mobile stations moving through vertical or horizontal domains need to be swift, to reduce the delays which degrade video streaming and voice-over-wireless local area networks. In this article, various roaming schemes are researched with a goal of reducing the long delays. These are exhibited particularly in mobile internet protocol schemes which suffer from the triangular routing of information via the home agent during handover of the session keys from the original access point to the targeted access point. In this article, opportunistic key caching forwards pairwise keys ahead of the mobile station prior to subsequent association. On the hand, pair-wise master key caching plays backward roaming where the cached keys available on both devices are utilized, thus, skipping reauthentication and only performing a four-way handclasp to legitimize the roaming client.
