Safety application system for mobile terminal to automatically switch between different channel networking interfaces

Abstract

The invention provides a safety application system for a mobile terminal to automatically switch between different channel networking interfaces. The safety application system can prevent the special data network from being directly connected with the Internet and avoid invasion of the Internet. According to the technical scheme, an application layer comprises a browser, a client terminal, an application program and an embedded channel switching program module. The special data network is constructed in the internal data network which is physically isolated from the Internet. The internal data network is connected with a VPDN special line or an APN network and at the same time, connected with the GGSN of the mobile network or the SGSN of a regional gateway. When the application layer detects the demand for switching to a different networking network, the embedded channel switching function module is called, the current Internet networking channel is closed, networking parameters of a networking sub-system of the current mobile terminal are rectified, APN networking parameters and / or VPDN networking parameters of the special data network are designated to the application layer and the networking request is provided.

Description

technical field [0001] The invention relates to a method for establishing a safe application system by using a dedicated wireless data network including an APN channel or a VPDN network, ensuring information security, and realizing switching between an Internet access channel and a safe application network channel on a mobile terminal. Background technique [0002] With the rapid development of the mobile Internet, all kinds of mobile applications emerge in endlessly, various illegal methods such as hacking and phishing websites infringe on the security of the Internet all the time, and the problems of various pre-installed software and virus packaging that threaten the security of mobile phone networks are becoming more and more prominent. Gradually formed a black industrial chain. The security of Internet application systems has increasingly become the focus of attention. After the Prism Gate, people found that in front of the US government with strong technical strength,...

Problems solved by technology

Remote access usually involves three parts: access terminal, access channel and intranet application. Failure to protect any of these three parts will bring security risks to the entire remote access process.

The traditional virtual private network-based mobile terminal access solution focuses on the establishment of secure transmission channels. Although it provides a guarantee for secure data transmission to a certain extent, it lacks protection for the entire access process and cannot meet the needs of enterprises and institutions for remote access to terminals.
