Embodiment Construction

[0046] The core idea of ​​the present invention is that the terminal sends a certificate status subscription request to the authentication service unit (hereinafter referred to as the authentication server) to obtain the status information of the WAPI certificate; The status information is included in the notification message and sent to the terminal, and / or within the validity period of the subscription, when the status of the terminal's WAPI certificate changes, the corresponding status information is included in the notification message and sent to the terminal.

[0047] In order to make the terminal know whether the state information of the WAPI certificate can be obtained, and the address used to obtain the state information of the WAPI certificate (that is, the address of the authentication server), the present invention adds certificate state management in the extended field of the WAPI certificate issued to the user structure. like figure 1 As shown, the certificate s...

Abstract

The present invention provides a method for obtaining the certificate state information and a certificate state management system, wherein the method comprises the following steps: transmitting the subscription request of WAPI certificate state information by a terminal to an authentication server of a wireless local area network for obtaining the state information of the WAPI certificate; and after the subscription request is received, if the authentication server determines that the terminal has the right for obtaining the state information of the WAPI certificate, the following procedures are executed: including the state information of the WAPI certificate obtained by enquiry when the subscription request is received in the informing information for transmitting to the terminal, and / orin the effective period of subscription, when the state of the WAPI certificate changes, including the state information of the WAPI certificate in the informing information for transmitting to the terminal. According to the invention, through initializing the subscription of the WAPI certificate state information, the terminal can obtain the WAPI certificate state information real-time actively.Furthermore the operations of certificate updating, etc. can be executed according to the certificate state information for facilitating the user.

Description

technical field [0001] The invention relates to the field of wireless local area network communication, in particular to a method for obtaining certificate state information of WAPI (WLAN Authentication and Privacy Infrastructure, wireless local area network authentication and privacy infrastructure) and a certificate state management system. Background technique [0002] WAPI is a wireless local area network security standard based on IEEE (Institute of Electrical and Electronics Engineers, Institute of Electrical and Electronics Engineers) 802.11 wireless protocol. The WAPI protocol consists of two parts: WAI (WLAN Authentication Infrastructure, wireless local area network authentication infrastructure) and WPI (WLAN Privacy Infrastructure, wireless local area network security infrastructure). WAI is a security scheme for identity authentication and key management in wireless local area networks. WPI is a security solution for wireless LAN data transmission protection, in...
