In this paper, we propose a method for proactive key
delivery to enable fast authentication as wireless LAN nodes
move between Access Points within an administrative domain.
The method optimises the EAP-TLS phase of the IEEE 802.11i
authentication process by creating list of keys at the first
authentication with the administrative domain, and proactively
delivering those keys to candidate Access Points. This takes
advantage of Proactive Context Transfer and Forced Handover.
The performance analysis shows that the proposal can reduce
significantly authentication delay and bandwidth consumption;
hence improve overall handover performance.
