SSL VPN-based secure information transmission method between mobile internet and private network

Abstract

The invention relates to an SSL (Secure Socket Layer) VPN (Virtual Private Network)-based secure information transmission method between a mobile internet and a private network, which comprises the following steps that: when accessing private network resources, a mobile terminal directly accesses all private network addresses without performing internet mapping, and the safety of private network interface addresses is ensured through confusion and reinforcement at the mobile terminal; the mobile terminal is integrated with a vpn tunnel, when a user logs in an App, whether the user can access private network resources or not is judged through secondary authentication, and the permission that the user meets the private network resources is judged; and after the Vpn tunnel is established, the internet access function of the user mobile terminal is cut off, so that the safety of the confidential data is improved. The method is developed from the four aspects of user and terminal legality, minimum / finest granularity permission control, behavior audit and exception handling and encryption algorithm effectiveness, and the safety from service to user end to end is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of network communication and network security, and in particular relates to an SSL VPN-based method for securely transmitting information between the mobile Internet and a private network. Background technique [0002] With the expansion of the application scope of the e-government business system, the e-government system is extending to the mobile Internet. Secure access is one of the important means to protect high-value information assets of business systems from being leaked. There are more and more high-value information assets in the user business system of the e-government system. Once leaked, the possible consequences are unimaginable. [0003] Due to the high cost of telecommunications dedicated line links and the security of information transmission, huge pressure has been placed on information construction. In order to ensure the validity and real-time performance of the data stored in the data c...

There are more and more high-value information assets in the user business system of the e-government system. Once leaked, the possible consequences are unimaginable

[0003] Due to the high cost of telecommunications dedicated line links and the security of information transmission, huge pressure has been placed on information construction. In order to ensure the validity and real-time performance of the data stored in the data center, many mobile apps have emerged to provide data collection and update. However, as an emerging development network environment, the mobile Internet has inherent deficiencies in security, and there are many potential safety hazards, which need to be highly valued and resolved; Government affairs systems also have information security issues
