High-performance mobile access gateway and method thereof connecting internal and external information networks

Abstract

The invention discloses a high-performance mobile access gateway connecting internal and external information networks, and a method thereof. The high-performance mobile access gateway comprises a front-end processor, an intermediate library and a rear-end processor, wherein the front-end processor is deployed in the external information network, is directly connected with an external network mobile application, and is connected with the intermediate library by means of an isolation device; and the rear-end processor and the intermediate library are deployed in the intranet information network, the rear-end processor is directly connected with the intermediate library, and the rear-end processor is directly connected with an internal network business application service. The access methodcomprises the steps that: the external network mobile application sends out an HTTP request; the HTTP request is written into the intermediate library by means of the isolation device after mapping proxy by means of the front-end processor; the rear-end processor polls the intermediate library to obtain the request and forwards the request to the internal network business application service, andthen writes a received response into the intermediate library; the front-end processor polls the intermediate library to obtain the response, and transmits the response to the external network mobileapplication, thereby realizing the penetration of the HTTP request from the external network to the internal network. The high-performance mobile access gateway and the high-performance mobile accessmethod ensure that all business services and data can be deployed in the internal network, thereby greatly reducing the complexity and difficulty of deployment of the external network mobile application.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a high-performance mobile access gateway and a method for connecting an information network with an internal and external network. Background technique [0002] With the improvement of automation level and the development of communication technology and network technology, major office systems rely more and more on information network to ensure the safe, reliable and efficient operation of their business and services. The security of information network is directly related to the security of the system, Therefore, it is particularly important to study the key technologies of system information security. [0003] To meet the security requirements of information network systems, physical isolation technology has been widely used in information network construction. A physical isolation device is set up between the information intranet and the information e...

AI Technical Summary

Problems solved by technology

There is a physical isolation device between the information intranet and the information extranet of the State Grid Corporation of China. Only SQL is allowed to penetrate the isolation device from the information extranet to enter the information intranet. Normal HTTP requests cannot reach the information intranet from the information extranet.

At present, the mobile application of the State Grid Information Extranet can only access the business application services deployed on the Information Extranet, but cannot directly access the services deployed on the Information Intranet

Therefore, in order to support the mobile application of the information extranet, each business system must deploy the corresponding mobile service on the information extranet, or even independently develop a set of mobile services that support the mobile application of the extranet, and cannot reuse the mobile service already built on the intranet. Application services, which undoubtedly increase the development cost of mobile applications on the external network, and deploying business application services on the information external network will bring the risk of data leakage and other security risks
