【摘要】 分布式文件系统是云计算研究领域内一个重要的分支,尽管分布式系统的分级安全功能的重要性很早就被意识到,但是在安全网络下进行分布式文件系统工作却极少。该文提出并设计基于分级安全局域网的分布式文件系统。采用主从式的结构,通过在客户端采取驱动式编程,用Reed-Solomen算法进行数据拆分存储,实现安全分布式文件系统的基本功能,包括数据传输、存储、数据加密、数据拆分、访问控制等。该系统性能测试实验结果满足多级安全局域网的性能要求。更多还原

【Abstract】 Distributed file systems(DFS) are an important branch of cloud-computing research.Although the importance of distributed system security has been recognized for a long time,there are few safe networks for distributed file systems.This paper describes a distributed file system for use in a classified secure local area network(LAN) environment.This system uses a main/slave structure with coding in the client-driver layer based on the Reed-Solomen algorithm to separate data.The system provides general DFS functions,such as storage,net transfer,data separation,data encryption and access control.Performance test results show that the system is fit for a secure LAN.更多还原
