Problems solved by technology

[0003] In the existing WAPI certificate authentication network, after the user goes online, if re-login, roaming, re-authentication, pre-authentication and other operations are performed, AE and STA will perform the WAPI certificate authentication process again, and the process is exactly the same as the user's first online process. The same, thus delaying the user's online time and reducing the wireless user's online experience

Embodiment 1

[0018] see figure 1 , Embodiment 1 of the present invention provides a WAPI authentication method, the method comprising:

[0019] 11. If the access point AP20 records the user certificate of the wireless terminal STA21 that needs to be authenticated, it sends an authentication activation packet to the wireless terminal STA21, and at the same time sends a certificate authentication request packet to the authentication service unit ASU22.

[0020] see further figure 2 For example, after the wireless terminal STA21 goes online for the first time, the access point AP20 records the user certificate of the STA21. When STA21 is associated or re-associated with AP20, if AP20 uses the WAPI certificate authentication and key management mechanism, then the AP20 judges whether the user certificate of the STA21 is recorded, if the user certificate of the STA21 is not recorded, then execute The usual certificate authentication process; if the user certificate of the STA21 is recorded, t...

Embodiment 2

[0025] see figure 2 , Embodiment 2 of the present invention provides a WAPI access point AP20, and the AP20 includes:

[0026] A certificate recording unit 201, configured to record the user certificate of the wireless terminal STA;

[0027] The certificate recording judging unit 202 is used to judge whether the certificate recording unit 201 records the user certificate of the wireless terminal STA21 to be authenticated;

[0028] Authentication packet sending and receiving unit 203, used for the certificate record judging unit 202 to determine that the certificate record unit 201 has recorded the user certificate of the wireless terminal STA21 to be authenticated, and at the same time send an authentication activation packet and a authentication packet to the STA21. The service unit ASU22 sends a certificate authentication request packet, and is further used to receive the access authentication request packet sent by the STA21 and the certificate authentication response pac...

Abstract

The embodiment of the invention provides a WAPI (Wlan Authentication and Privacy Infrastructure) authentication method and an access point for a wireless local area network authentication and confidentiality base structure. The method comprises the following steps: an access point sends an authentication activation packet to a wireless terminal and simultaneously sends a certificate authentication request packet to an authentication service unit; and the access point carries out corresponding authentication operation after receiving the access authentication request packet and a certificate authentication response packet. According to the WAPI authentication method provided by the embodiment of the invention, by adopting a parallel certificate authentication flow, message waiting time for the whole authentication flow is shortened, the certificate authentication flow is quickened and the online experience of the user is improved.

Description

technical field [0001] The invention relates to the field of network communication, in particular to an authentication method and an access point of a WAPI (Wireless LAN Authentication and Privacy Infrastructure) of a wireless local area network. Background technique [0002] WAPI includes a new security mechanism for wireless authentication and encryption infrastructure, consisting of two parts: WAPI (WLAN Authentication Infrastructure) and WPI (WLAN Privacy Infrastructure). WAPI implements identity authentication of users, and WPI implements encryption of user data. There are two authentication methods for WAPI user identity authentication, pre-shared key (pre-shared key, PSK) and certificate. The pre-shared key method is the same as the pre-shared key of other wireless authentication strategies, only need to configure the same on the authenticator entity AE (Authenticator Entity) in the wireless terminal STA (STAtion) and access point AP (Access Point) key. The certifi...
