Embodiment Construction

[0041] The IP Multimedia Subsystem is a set of specifications that describe the architecture of Next Generation Networks (NGN), which are used to enable IP-based telephony and multimedia services. IMS defines a complete set of architecture and framework, allowing voice, video, data and mobile network technologies to be aggregated on an IP-based infrastructure. It uses SIP (Session Initiation Protocol) and has access-independent features.

[0042] In the present invention, the terminal accesses the IMS network through the 3G RAN and after successful registration, sends an HTTP message to the registration server to obtain the WAPI certificate. After receiving the HTTP message, the registration server forwards it to the authentication server corresponding to the terminal. The server returns the WAPI certificate, and the registration server forwards the WAPI certificate to the terminal. After receiving the WAPI certificate, the terminal can perform the certificate authentication pr...

Abstract

The invention discloses a method for acquiring a WLAN authentication and privacy infrastructure certificate, comprising the steps as follows: a terminal sends a certificate issuing request to an authentication server; and the authentication server searches the WAPI certificate of a user according to the account of the user of the terminal carried in the received certificate issuing request and sends the found WAPI certificate to the terminal. In the invention, before carrying out the first certificate authentication, the terminal is accessed to the IMS network by 3G RAN, and acquires the WAPIcertificate by the signaling interaction between the IMS network and the authentication server; the invention avoids the inconvenience of the user in acquiring the certificate by an off-line mode andsimplifies the certificate management process of the users and operators and the process that the terminal acquires the certificate by running background, thereby improving the user experience.

Description

technical field [0001] The invention relates to the technical field of wireless local area network, in particular to a method and a system for obtaining a wireless local area network identification and security infrastructure certificate. Background technique [0002] WAPI (WLAN Authentication and Privacy Infrastructure) is a wireless security standard based on the 802.11 wireless protocol proposed by China. The WAPI protocol includes two parts: WAI (WLAN Authentication Infrastructure, wireless local area network identification 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 It is a security solution for data transmission protection in wireless LAN, including functions such as data encryption, data authentication and replay protection. [0003] A typical WAPI system mainly includes an authenticator entity (AE...
