Design And Implementation Security Module Of Data Transmission Platform On Distributed System

With the rapid development of information technology, information management platformupon distributed environment is increasing rapidly, which result in plenty of distributedbusiness data increasing. Dispersed storage reduce the efficient use among systems. The datacan be shared with network with using distributed system. But the secure transfer of those datais an important guarantee of Distributed System, because the openness and insecurity ofnetwork. So strategies for data transmission safely of play an important role in distributedsystem.Based on distributed environment of data transmission, also not only the confidentiality,the integrity and the nonrepudiation should be taken into account, the speed also should paymore attention to, according to the demand of the urgency of data. This article takesmanagement operating system for higher education examination of Shandong Province base oninternet as the background，has designed and implemented a data transfer strategy upon securitymodule of data transmission platform.On one side, use HPROSE as the transmission medium. There exist many transmissionprotocols at home and abroad，such as SOAP protocol which is more pop in the enterpriseapplication at present. But in this paper the design select HPROSE as the transmission medium.HPROSE, a new remote dynamic communication middleware of China, is a lightweightmiddleware in cross-language and cross-platform，which is fit for distributed environment, andsupport the intercommunication among many languages, efficient and convenient and fast.Besides, HPROSE use PHP serialization instead of XML, which is better than SOAP intransmission rate.On the other hand, the paper implements identity authentication with Spring SecurityFramework to make sure that data can only be transferred among those who have authority totransfer data; use AES algorithm of128bits and RSA algorithms of1024bits, together withDigital Digest and Digital Signature technology, making the confidentiality, the integrity andthe nonrepudiation of transmit Data; Meanwhile, design transmission levels, casting to theneeds of the costumer for transmission rate, within the scope of the license of the needs emergency degree and the safety degree for data. Customers can choose the level, which meettheir high level of satisfaction rate, to transfer data on their demands with the Function ofBroken-point Continuingly-transferring.Finally, analyse the advantages and disadvantages among the direct connect to databasefor data transmission, the SOCKET communication to transmit data and through file form fordata transmission, and ensure file form transmission as the transmission of this datatransmission scheme and implement it.
