Design And Implementation Of Secure File Interchange System

With the continuous development of information technology,most enterprises have applied different development languages,heterogeneous software and hardware platform to build many mature business information systems.These systems produce large amounts of business data.In order to make full use of these data assets for realizing enterprise data sharing,the systems need to carry on the data interchange.In this context,this thesis proposes a data interchange platform based on flat file,secure,lightweight,generality and near zero cost,secure file interchange system(SFIS).Each application system is associated with SFIS by using uniform data interchange standard.SIFS bases on distributed operation to realize data sharing.It ensures security of the file transmission by applying independent intellectual property rights and high security application with the state secret algorithm SM3 and SM4,and the security of cryptographic protocols.When the file transfer successfully completed,time arrivals,or work conditions such as trigger events,they notify the scheduling engine without polling scheduling.Scheduling engine execute job according to the cluster node's computing ability and the task,resource load,job priority and other factors.SFIS can monitor the running state of cluster job scheduling engine,execution node through the HTTP server,file transfer and job execution information.At the same time through the reverse proxy server,it can monitor the system in office environment.The main functions of the system are unifying data file interchange process and rules,providing a unified real-time data sharing service,realizing secure transmission of data files,management of data exchange work flow and scheduling,management of node resource and system monitoring.Through the application of SFIS,this thesis solves the problem of data exchange between enterprise application systems with extremely low cost.It can eliminate the island of data and realize the data security sharing.Through the implementation of SFIS,it lays a solid technical and theoretical basis for understanding or realizing cryptographic algorithm and cryptographic protocol,information security,data structure,system programming,network programming;web server,the reverse proxy server,the data integration platform,big data,cloud computing platform and so on.
