Fast and secure authentication in IEEE 802.11i wireless LAN

Abstract

Authentication has become a major problem in wireless network communication; since this technology enables its client to communicate each other through radio wave. This kind of communication makes user intercept the traffic easily. When wireless implements high level security standard such as IEEE 802.11i to tighten its authentication mechanism, it deals with long delay in handover. To support fast handover, pre-authentication mechanism has been proposed. This paper compares pre-authentication method in terms of architecture, and its performance in handling the delay in handover.
