Method and system for roaming non-aware network access authentication based on virtual network

Abstract

The invention discloses a roaming non-aware network access authentication method based on a virtual network, which comprises the following steps: acquiring a terminal identification and terminal related information in a wireless network system; generating user network identification information based on the terminal identification and terminal related information ; Create a user virtual network based on the user network identification information; the terminal establishes a network connection with the virtual network, and the authentication link obtains a user preset key from the cloud based on the terminal identification and the user network identification to complete the authentication during the connection process. It is used for mobile terminals to automatically access the nearest network and perform security authentication in the roaming state, and perform secure communication without the user's awareness.

Description

technical field [0001] The invention relates to a terminal network access authentication method, in particular to a virtual network-based roaming non-aware network access authentication method and system. Background technique [0002] With the rapid development of the mobile Internet, the rapid popularization of mobile terminals has brought great convenience to people's work and life. The Internet access of mobile terminals is subject to the bandwidth and traffic limitations of the mobile communication network, and the WiFi wireless network based on the 802.11 protocol is a very cost-effective Internet access method, which has been widely deployed and used. However, in the roaming state, the WiFi network authentication method based on the 802.11 protocol greatly limits the user access experience and also brings about network communication security issues. [0003] In order to solve this problem, the most common solution at present is to authenticate access through Web Porta...

[0004] However, Web Portal authentication access needs to perform Web Portal user authentication each time the network is accessed, which increases user operation time and reduces user access experience; on the other hand, Web Portal authentication access is Communication through an open network is easy to be camouflaged to steal user account password and other information, and the communication process is also easy to be intercepted by the network, which brings great security problems.
