DESCRIPTION:Wireless sensor networks are becoming popular in medical monit
 oring and require higher levels of security. In this presentation\, I will
  present a security architecture to provide authentication and key managem
 ent for medical sensor networks. Widely used EAP authentication framework 
 is extended and the GPSK authentication method is optimized for securing t
 he system. Three-party EAP model with PAN coordinator as the authenticator
  is used for authenticating PAN coordinator's first-hop neighbors. For dis
 tant nodes\, relay authenticators are used for tunneling EAP messages from
  supplicants to the authenticator and vice-versa. The EAP encapsulation fo
 r WPANs and a key hierarchy are proposed for the system. The system is sim
 ulated using NS-2\, which shows that EAP based security protocol is feasib
 le in WSNs. \n\nThis talk is my master thesis from University of Northern 
 British Columbia\, Canada.\n\n\n\n\n
