Study On Cloud Computing's Application In File Management System Of Primary And Middle School Students

With the continuous progress of science and technology in our country,people's living standards improves andit puts forward higher requirements for the quality of education and teaching at the present stage,devoting more energy to the future education of children.The increasing maturity of cloud computing technology is in line with the goal of modern educational reformation,the application of cloud computing to the management system of the primary and middle school students' growth,on the one hand,it can improve the quality and efficiency of teaching;on the other hand,it also record performance of the students in all stages of school,making teachersandparents understand each student's learning and other performancecomprehensively.This is a dynamic,constantly updated data recording process.Based on the analysis of the development and current situation of the traditional student archives management system,this paper designs and implements a archives management system based on cloud computing for primary and middle school students.The system is mainly developmentedin the Java platform of J2 EE,using B/S framework to achieve.At the same time,we use Hadoop technology framework,the aim is to construct a distributed system with high reliability and good expansibility,which can realize the parallel computation and storage of massive data.The system has realized the basic information,the curriculum arrangement,the growth track,the test result,the educational administration feedback and so on,and the system framework of cloud computing environment is designed and studied,including data framework,security system framework,database structure design,etc..Additionally,as per data safety problems of cloud storage in primary and middle school students' portfolio records,it brings forward a Ciphertext-policy attribute-based encryption(CP-ABE)fine grained access control.Which is applied with hybid encryption algorithm that based on Data Encryption Standard(DES)and CP-ABE,namely to use DES encrypts the big database first and CP-ABE encrypts the symmetric key follows.Finally,whichtests each functional module of the system.Test results show that,the design of student archives management system based on cloud computing has achieved certain expected results.For this module of data security issues,experiment shows that distributed environment,this scheme will take a bigger advantage in completeness,privacy and efficiency of cloud storage database.
