NETWORK SYSTEM FOR IMPROVING NETWORK SECURITY IN A NETWORK ENVIRONMENT THROUGH IEEE 802.1X AUTHENTICATION AND AN AUTHENTICATION METHOD USING THE SAME

摘要

PURPOSE: A network system and an authentication method using the same are provided to perform an authentication process by using standard technology based on IEEE 802.1X.;CONSTITUTION: A network system(100) includes a client(102), an IEEE 802.1x non-supported switch(104), an enforcer(106), and an authentication server(108). The client can be a digital device including a PC(Personal Computer), a notebook, a PDA(Personal Digital Assistant), and a mobile phone. The IEEE 802.1x non-supported switch performs only a function of transferring packets mutually transmitted between the client and the enforcer. The enforcer performs an authentication process with the authentication server. The enforcer transfers an authentication result to the client through the IEEE 802.1X non-supported switch.;COPYRIGHT KIPO 2012
