Embodiment Construction

[0031] The present invention includes a link-level authentication step and an account information authentication step, wherein the link-level authentication step is as follows:

[0032] 1) The server issues the same certificate for all mobile terminals, and issues a certificate for each wireless access point, wherein different wireless access points issue different certificates, and the mobile terminal and the wireless access point install the certificate issued by the server;

[0033] 2) When the mobile terminal needs to access the network, the mobile terminal first associates with the wireless access point and establishes a link connection;

[0034] 3) After the mobile terminal is associated with the wireless access point, the wireless access point sends an authentication activation frame to the mobile terminal to start the authentication process;

[0035] 4) According to the national standard GB 15629.11 and its amendment No. 1, mobile terminals and wireless access points a...

Abstract

A WLAN authentication charging method based on WAPI includes the steps: a same certificate is issued to all mobile terminals, different certificate is issued to each radio access point. When a mobile terminal accesses a network, the mobile terminal associates to a radio access point, and establishes a link connection. The certificate of the mobile terminal and the certificate of the radio access point associated to the mobile terminal are authenticated. When the certificate authentication is successful, the mobile terminal and the radio access point negotiate session keys, the radio access point notifies multicast keys to the mobile terminalto allow the mobile terminal access. After the mobile terminal accesses the network, the account information of the mobile terminal is authenticated. The authentication information of the mobile terminal is obtained according to the result of the account information authentication so that the mobile terminal can access the network. According to the present invention, the operation management of the WLAN is in conformity to original operation network, the bi-directional identity authentication between the user and the network can be realized, and the original authority, charging system can be compatible to, and the related standards are supported.

Description

technical field [0001] The invention relates to the field of wireless local area networks, in particular to a method for realizing WLAN operation based on WAPI by using a terminal certificate. Background technique [0002] WLAN (Wireless Local Area Network) has developed rapidly in recent years due to the flexibility, speed and scalability of its architecture, and has been widely used in hotspot area operations, enterprises, industries and homes. [0003] For wireless LANs, security is of paramount importance. In May 2003, my country promulgated national standards for wireless LANs GB15629.11 and GB15629.1102, which were the first batch of standards issued by my country in the field of wireless LANs. In 2006, GB15629.11-2003 / XG1-2006 and other relevant sub-standards GB15629.1101, GB / T15629.1103 and GB15629.1104 were promulgated and implemented in the No. standard system. The standard system includes a new WAPI (WLAN Authentication and Privacy Infrastructure) security mech...
