Authentication method, system and equipment for network access

Abstract

The embodiment of the invention discloses an authentication method for network access, an authentication system for network access and a piece of authentication equipment for network access, which are applied to the technical field of communication. In the authentication method for network access disclosed by the embodiment, a data transmission passage is built between a piece of first wireless access network equipment and a first wireless access network of a piece of user equipment (UE), after the identification information of the UE at a second wireless access network is acquired, the authentication information of the second wireless access network corresponding to the identification information is generated, wherein the authentication information comprises the authentication information of the second wireless access network which is used by the UE and a piece of second wireless access network equipment; the authentication information used by the UE is transmitted to the UE, and the corresponding relation between the identification information and the authentication information which is used by the second wireless access network equipment is transmitted to the second wireless access network equipment. Therefore the authentication information for network access authentication is difficult to be disclosed, and the safety of network access authentication is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an authentication method, system and equipment for network access. Background technique [0002] In a wireless access network such as a wireless local area network (Wireless Local Area Network, WLAN), in order to solve the problem of network security, a unified authentication method is generally used to authenticate users in the wireless access network, so that the user equipment can use the user name and Token login access to the network system that is allowed to log in. Existing unified authentication methods include an authentication method based on an Extensible Authentication Protocol Method for GSM Subscriber Identity Module (EAP-SIM), a Portal authentication method, and a wireless-based authentication method based on an extensible authentication protocol. A pre-shared key (Wi-Fi Protected Access, Pre-Shared Key, WPA-PSK) authentication method for protecting...

Problems solved by technology

[0004] The premise of the above-mentioned existing authentication is that both the authentication terminal and the user equipment need to be configured with authentication information. For example, the premise of WPA-PSK authentication is that the same shared key and the same Algorithm and other authentication information, so it is easier to leak authentication information; and if the authentication information is leaked, it is necessary to manually reconfigure the authentication terminal and user equipment, which is cumbersome
