基于分布式存储系统的数据认证和安全保障研究

Data Authentication and Security Assurance Based on Distributed Storage System

在业界通用的分布式存储系统中,对于数据安全性的防护是薄弱和缺失的。在其被用于解决云端的数据存储时,由于数据安全性要求较高,这一问题极为明显。本文以HDFS系统为例,提出了一种有效的基于分布式存储系统的数据安全保障方案。方案为文件存储提供AES加密机制,给出一种能够与分布式计算系统无缝结合的文件加密格式,同时提出了一种基于涉密数据的授权鉴权方式,并持续监控审计。

In the general distributed storage systems,lack of data security measures is a serious problem.Due to the high demand of data security,it＇s difficult to deal with security issues in Cloud storage by the distributed storage systems.An Effective data security scheme based on distributed storage system is proposed,in which the AES encryption mechanism is used in document storage.The File encryption format in this scheme can be combined seamlessly with distributed computing system.This scheme also proposes an Authorization mode based on confidential data,and the data will be monitored continuously.
