Authenticated Analysis And Applied Research About EAP-TLS In802.11i

At present, the wireless local area network is a wireless network with the most development potential, the network application in portable terminal more convenient, because wireless network for space communication, the communication medium is open, making it more vulnerable to illegal intrusion, which leads to hackers, therefore the establishment of a sound, safe wireless local area network be imperative.This thesis deeply discusses the wireless LAN standard, analyzes the security threats in wireless. LAN exist, focuses on the serious security flaws in the WEP protocol and the authentication mechanism in wireless network security mechanism, and has carried on the thorough analysis to the IEEE802.11i standard from the confidential data protocol, dynamic key management and authentication and access control of the three aspects; and then the analysis and improvement of EAP-TLS authentication mechanism, one is the analysis and safety certification process, two is compared with other typical authentication mechanism, three is the analysis of the EAP-TLS security authentication flaw, the recommendations for improvement, and use OPENET simulation validate the improvement effect, this improvement is of positive significance on DoS attack defense from end. After the implementation of EAP-TLS certification is designed, including the certificate generation, client authentication server authentication process analysis, process analysis. Finally EAP-TLS certification in Xunkao implementation of the system, including the examination inspection information security and customer in the system demand analysis and EAP-TLS multiple CA environment Linux configuration.24figures,3tables,51references.
