基于Spark的校园文档加密系统的设计与实现

Design and Implementation of the Campus Document Encryption System Based on Spark

文章主要针对学校的大量电子机要文档,设计了一个基于Spark的校园文档加密系统。该系统在搭建Spark平台的基础上,使用分布式文件系统(Hadoop Distributed File System,HDFS)存储文档,并将文档使用高级加密标准(Advanced Encryption Standard,AES)算法进行加密和解密,能够满足500~1000个用户同时对各类重要文档进行加密和解密操作,不仅提高了数据的安全性,而且给工作人员提供了极大便利。

This article mainly designs a campus document encryption system based on Spark for a large number of electronic confidential documents in schools.Firstly,this system builds a Spark platform,then uses the Hadoop Distributed File System(HDFS)distributed file system to store documents.At the same time,we uses the Advanced Encryption Standard(AES)encryption algorithm to encrypt and decrypt the documents.This system can meet the requirements of 500 to 1000 users simultaneously encrypting and decrypting various important documents,not only improving the security of data,but also providing the extremely convenience for staff.
