System and method supporting rapid access authentication

Abstract

The invention discloses a system and method supporting rapid access authentication. The system consists of an equipment terminal, an access point (AP), and an authentication server. The authentication server includes an interface, a processing unit, a user authentication list, an address authentication list and an IP address pool. According to the method utilizing the authentication server to realize rapid access authentication, when the equipment terminal handovers a control domain of the AP or log in again, the authentication server searches the address authentication lists of the equipment terminal; if an IP and an MAC address that are matched to the equipment terminal are found, the authentication is passed; otherwise, the user is required to input a user name and a password again; and then the authentication server searches the user authentication list; if a matched user name and a matched password are found, the authentication is passed; otherwise, the authentication fails; and the authentication server makes a request of re-inputting of the user name and the password. According to the invention, time for re-authentication of access is substantially shortened and the communication quality is improved. And a user is only required to input a user name and a password during first-time authentication and there is no need to carrying out repeated inputting for subsequent handover and re-logging in.

Description

technical field [0001] The invention relates to network authentication technology, in particular to a system and method supporting fast access authentication. Background technique [0002] With the rapid development of communication technology, people have higher and higher requirements for communication quality, especially after the emergence of wireless communication, mobile communication has gradually become the first choice for people's daily entertainment and office work. However, when the device terminal moves from the control domain of wireless AP1 to the control domain of wireless AP2, the network communication will be temporarily interrupted, resulting in the suspension of communication services, and the user needs to re-login and authenticate to continue communication, which is very important for real-time It is unbearable for demanding users. [0003] The currently adopted method for a mobile terminal to access a wireless network is to first set an IP address fie...

However, when the device terminal moves from the control domain of wireless AP1 to the control domain of wireless AP2, the network communication will be temporarily interrupted, resulting in the suspension of communication services, and the user needs to re-login and authenticate to continue communication, which is very important for real-time Unbearable for demanding users

[0003] The currently adopted method for a mobile terminal to access a wireless network is to first set an IP address field in a wireless AP (Access Point), and then use DHCP to automatically assign a temporary IP address to a device terminal to access the wireless AP, and at the same time assign The user name and password for the device terminal to access the wireless network can only be connected to the wireless network after passing the authentication of the authentication server. address, at this time, the wireless AP2 needs to reassign a temporary IP address to the device terminal automatically. During the period when the device terminal reacquires the IP address, the communication service is interrupted.

In addition, every time a user logs in, he must enter a user name and password to access the network, and the user experience is not good.
