Data interaction method and system

Abstract

The embodiment of the invention provides a data interaction method and system. The system includes a first unidirectional gatekeeper, a second unidirectional gatekeeper, a first proxy server, a second proxy server, a resource server, and a client. The first proxy server and the client are both located in a first network. The second proxy server and the resource server are both located in a second network. The first network is physically isolated from the second network. The first proxy server is configured to receive a request sent by the client, to send the request to the second proxy server via the first unidirectional gatekeeper, and to send a response message to the client. The second proxy server is configured to send the request to the resource server and to receive a response message returned from the resource server, and to send the response message to the first proxy server via the second unidirectional gatekeeper. Because the unidirectional gatekeepers transmit data unidirectionally, the first network and the second network are safely isolated, thereby ensuring the data security of the first network during data interaction.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data interaction method and a data interaction system. Background technique [0002] With the continuous development of network technology, more and more schools and business units have established local area networks to realize file management, application software sharing, printer sharing, scanning sharing, scheduling within workgroups, email and fax communication services and other functions. [0003] Usually, some enterprises allow their internal computers to access other networks except the enterprise LAN, and also allow other networks to access their LAN; however, it is easy to cause leakage of enterprise information. There are also some enterprises, such as the Public Security Bureau, which do not allow their internal computers to access other networks other than the enterprise LAN, such as the Internet. Unable to obtain the required information in a ti...
