Guoying Zhang · Journal of Kunming University of Science and Technology · 2007
In this paper,by capturing frame between supplicant and authenticator,and developing compatible supplicant using WinCap,Ethernet access control technology,802.1x,especially Huawei 802.1x,is analyzed.Then in order to keep subscriber away from invalid supplicant,a method is proposed for detecting supplicant version.This checking version method is based on challenge authentication,and transmits different checking version frame from an original random number between authenticator and supplicant when authentication has started.It determines the supplicant version by removing the playback attack source data of invalid supplicant.
