Problems solved by technology

Since the WAI protocol can only support certificate authentication, if user authorization and accounting processing are required, an AAA server needs to be deployed in addition to the AS server, which increases the complexity of the deployment, and because the AAA server also has authentication functions, at the same time In order to avoid the unnecessary authentication process of the AAA server, it will increase the complexity of device processing

Embodiment Construction

[0050] figure 2 It is a flow chart of a WAPI authentication method in the present invention. The WAPI authentication method is applied to a system including an access point and an authentication server, wherein the access point can be regarded as a kind of authentication device (also can be regarded as a commonly-called authentication client), such as figure 2 shown, including the following steps:

[0051] Step 201, the authentication server receives a WAI authentication request message sent by an access point, the authentication request message carries WAI group information, wherein the WAI authentication request message is encapsulated in a RADIUS message. Wherein, the manner of carrying the WAI group information is: extending the Vendor-Specific attribute of RADIUS, and carrying the WAI group request or response information in the Vendor-Specific attribute.

[0052] The specific implementation method is to add an extended attribute in the RADIUS protocol, which carries ...

Abstract

The invention discloses a method for WAPI authentication, which is used for a system comprising an authentication device and an authentication server. The method comprises the following steps: receiving a WAI authentication request message sent by the authentication device, wherein the authentication request message carries WAI grouping information, and the WAI authentication request message is encapsulated in an RADIUS message; and carrying out the WAI authentication on the authentication device based on the WAI grouping information and returning the WAI authentication results to the authentication device by a WAI grouping response message, wherein the WAI grouping response message is encapsulated in the RADIUS message. In the invention, the certificate authentication can be carried out as long as an authentication server is allocated, thereby facilitating the user authorization, charging, system allocation and device processing. The invention also discloses a system and a device for WAPI authentication.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method, system and equipment for realizing WAPI authentication. Background technique [0002] WAPI (WLAN Authentication and Privacy Infrastructure, wireless local area network authentication and privacy infrastructure) is a protocol for realizing wireless local area network security. WAPI adopts the elliptic curve cryptography algorithm of the public key cryptography system and the block cipher algorithm of the symmetric cryptography system, and is used for the encryption and decryption of digital certificates, certificate authentication, key negotiation, and transmission data of WLAN (Wireless Local Area Network, wireless local area network) devices, thereby Realize device identity authentication, link verification, access control and encryption protection of user information in wireless transmission state. [0003] WAPI is the collective name of two protocols, WAI (WL...
