基于云计算技术环境的网络安全存储系统设计研究

Research and Design of Network Security Storage System Based on Cloud Computing Technology Environment

云计算技术的发展使得存储安全性成为该领域关注的重点问题之一,采用安全有效的访问控制技术是云存储系统安全性提升的重要手段。本文提出一种用于解决云计算环境下网络安全存储系统的安全性-基于语义的访问控制系统,该系统使用访问代理模块来评估基于使用组织机密性策略生成的规则的访问决策。在做出访问决定之前,所提出的系统分析发出请求的用户的多值属性和存储在云服务平台上的所请求的文档,通过从不受信任的云服务提供商处隐藏其访问模式详细信息。

The development of cloud computing technology makes storage security one of the key issues in this field. The adoption of secure and effective access control technology is an important means to improve the security of cloud storage systems.This paper proposes a security-based access control system for solving network security storage systems in cloud computing environments. The system uses access agent modules to evaluate access decisions based on rules generated using organizational confidentiality policies. Before making an access decision, the proposed system analyzes the multi-valued attributes of the requesting user and the requested documents stored on the cloud service platform by hiding their access mode details from the untrusted cloud service provider.
