Research And Implementation Of Data Secure Bidirectional Transimission Technology

With the rapid development of Internet,all walks of life are accelerating the pace of information construction.In order to ensure the steady progress of enterprise information construction,the information security requirements of enterprises in the construction of information system are increasing.In order to make network attacks fundamentally blocked from the network that needs to be protected,network isolation technology emerges as the times require.For the government network system and the power enterprise network system,with high information security requirements,it is necessary to put secret information in a proprietary network and isolate it from other networks.The data secure bidirectional transmission technology realizes the efficient,safe and stable data exchange on the basis of isolation and shielding of different networks.This paper firstly analyzes the serious network security problems faced by the current information society,and summarizes the research status of the different network security data exchange problem at home and abroad.As a result,the basic route of the realization of data secure bidirectional transmission is using network isolation technology.Then,it analyzes the advantage of data transmission in manual copying mode,that there is none of network attack,and analyzes the disadvantages that its transmission speed is slow and the fact that copy contents and processes cannot be controlled.Based on protocol analysis technology,zero copy technology and thread pool technology,the data secure bidirectional transmission system,which has the advantages of data transmission,that there is no network attacks and the transmission speed is high enough,and the access to business and the transfer content is strictly controlled,can be achieved of cross-platform efficient,safe and stable data exchange in different networks.Finally,the system test shows that the system function conforms to the design concept.It can only make the application data which compatible with the application access control policy and the data template,and it is able to process large amounts of concurrent data efficiently.The research and implementation of data secure bidirectional transmission technology has very important practical significance for the comprehensive improvement of enterprise information level.
