An EAP_TTLS_SPEKEY Method for Single EAP_Based Auth Mode of IEEE 802.16e PKMv2

IEEE 802.16e Standard as the new released version, renew the security scheme PKMv1 of IEEE802.16d into PKMv2. This paper analyzes the EAP_based authentication mode of PKMv2, and proposes an improved EAP_TTLS _SPEKEY method for EAP_based authentication patter. The improvement has enabled the EAP_TTLS_SPEKEY to overcome the engrained vulnerability of the Man in the Middle attacks in the original EAP_TTLS design.
