Method for realizing radio local area network authentication

Abstract

This invention discloses a method for performing authentication in a wireless LAN, applying to a wireless roaming mobile network which consists of a wireless LAN and a home location register (HLR) at least, subscriber terminal (STA) physical connects with an access point (AP), the core idea of the method of: in a multi-mode network, setting up a server (U-AAA) for authenticating, granting and charging the user identification module, subscriber information in the user identification module of STA is used as the subscriber identifier, according to the subscriber identifier, U-AAA extracts the authentication aggregation from the HLR of the mobile network which supports wireless roam, then through the random number generated by the STA and the authentication number corresponding to the authentication aggregation in the HLR of the mobile network which supports wireless roam, performing the mutual authentication between the subscriber terminal and U-AAA. This method is simple, convenient for application, cost-effective, safe and highly reliable.

Description

technical field [0001] The invention relates to network authentication technology, in particular to a method for authentication when a WLAN user accesses the network in a wireless roaming mobile network including at least a WLAN network and a home location register (HLR). Background technique [0002] WLAN uses radio frequency (RF) technology to form a local area network, which is a convenient data transmission system. In June 1997, the first wireless local area network standard IEEE802.11 was officially announced, which provided a unified standard for the physical layer and media access control (MAC) layer of wireless local area network, and strongly promoted the rapid development and application of wireless local area network. [0003] The identification and authentication of WLAN users generally depend on the unique account number and its corresponding password in the network. Through the authentication center, such as the remote access dial-up user service protocol serve...

AI Technical Summary

Problems solved by technology

[0020] 1) Only AAA authenticates STA, which has low security;

[0021] 2) The initial key is statically configured, and the security of data transmission is not high;

[0022] 3) Operation and maintenance are inconvenient and costly
