分布式文件系统数据安全机制研究

Research on Data Security Mechanism of Distributed File System

在介绍几种分布式文件系统在解决数据安全方面采用的手段和存在的不足基础上,根据分布式文件系统的特点,设计并实现一个OFS安全框架。通过引入PKI身份认证机制、文件加密访问机制、数据完整性验证机制,研究设计一种OFS安全框架,并对设计的OFS安全框架进行分析。

In the introduction of several distributed file system used in the data security measures and in- sufficient basis, according to the characteristics of distributed file system, designs and realizes a OFS security framework. By introducing the PKI authentication, encrypted file access mecha- nism, data integrity verification mechanism, studies and designs a OFS security framework, and analyses the OFS security framework designed.
