Design And Implementation Of Imformation Management System For Internet Spaceflight Equipment Based On Imformation Integrity

At present,the management of aerospace equipment in Beijing Aerospace Propulsion Institute relies heavily on the traditional way of handwritten documentation.This management approach is quite time-consuming to register the basic information of the equipment,as well as in recording its operation and maintenance status.Besides,information sharing and exchange are unsmooth between the two sets of network environment used in Beijing Aerospace Propulsion Institute,which greatly reduce management efficiency and impede technology development.In order to ensure the efficiency,accuracy,stability and security of data query,storage and transmission,it is necessary to customize a new information management system of aerospace equipment.In the paper,the technology of J2EE and AWS BPM process engine are used to implement information vetting and archiving,which are deployed in the environment of Windows Server 2008,while the framework of the system is formed on the basis of the MVC three-tier architecture.Concerning the dual-network operation feature of Beijing Aerospace Propulsion Institute,this paper adopts the ferry system to realize seamless process of information,and establishes a hybrid encryption signature scheme with high encryption efficiency and strong robustness to prevent the outflow of the secret data in the process of circulation,which ensures the information integrity in data storage and transmission.The demands analysis of building such an equipment information management system and the process of research and development are detailed described in the paper.Test results show that the equipment information management system operates stably and reliably.It solves the dilemma of equipment management in Beijing Aerospace Propulsion Institute by reducing duplicated work while increase information security.In summary,this system well improves work efficiency as expected.
