Analysis And Solutions Of Campus Wireless Lan Security Certification Based On Wapi

Networks can make people access shared resources by any ways and at any area and any time. As its flexibility and convenience, Wireless Local Network is widely used in schools, hospitals, airports, hotels, convention centers, stadiums, and other hot spots. However, due to the use of an open wireless LAN wireless transmission media will allow him to face many security threats. For example, the data is more vulnerable to eavesdropping, interception or tampering, wireless devices more vulnerable to denial of service, fake attack, and so on.First introduced the wireless LAN knowledge and relevant standards, describes the security requirements of wireless LAN and security issues. After, describes the wireless LAN security technology:There are encryption, identity authentication and access control technology.Secondly, presents and analyzes China's WAPI standard wireless LAN security authentication protocol. WAPI is a national standard GB15629.11 used in security mechanisms, by the WAI and WPI of two parts, namely, to achieve the user identity authentication and encrypted transmission of data. Detailed the port-based authentication process to access the WAI. WAPI be able to provide users with comprehensive security.Then, WAPI may have been aimed at the middle attacks, making suggestions for improvements.Lastly, given a solution of the campus wireless LAN based on WAPI.
