Data security transmission system and method based on data gateway

Abstract

The invention relates to a data security transmission system based on a data gateway. The system comprises a plurality of PC terminals and a plurality of service system servers, wherein the PC terminals and the service system servers perform bidirectional data transmission through data gateway equipment. Data gateway software is installed in each service system server. Before a PC terminal accesses the service system server, data gateway software needs to be installed in the PC terminal; the data gateway equipment performs trust judgment on the PC terminal, adds a private protocol data head toa service data packet received from the PC terminal and transmits the service data packet to a service system server when the service data packet is confirmed to be a trusted terminal; the service system server analyzes and judges whether the data packet is reported by the data gateway equipment or not, and if not, the service system server intercepts the data packet and returns an unauthorized access data packet; and if yes, the service system server analyzes the data packet, performs service response processing and then returns a response data packet, so that the method is safe and efficient. The invention also relates to a data security transmission method based on the data gateway.

Description

technical field [0001] The invention relates to the technical field of computer information security, in particular to a data gateway-based secure data transmission system and method. Background technique [0002] With the development of Internet technology and the rapid update of information technology, as the needs of biochemistry and work become more diversified, complex and refined, in order to meet the latest needs, enterprises in all walks of life have developed and expanded their own business systems, enhanced Its own business capabilities, and now many business systems in various fields, such as enterprise ERP systems, OA systems, etc., are all server-client architectures. When users need to access the business systems of the server, they will use PC terminals and The business system of the server performs information interaction. This operation cannot guarantee whether the PC terminal is in an absolutely safe environment when accessing the business system, and canno...
