【摘要】：随着云存储的迅速推广,有越来越多的用户开始使用网盘系统存放数据.然而,最新的研究结果却表明:现有网盘系统普遍存在着安全漏洞.近年来,网盘泄漏用户数据的事件更是印证了这些漏洞的存在.为此,提出一种云存储环境下的安全网盘系统架构,并在此架构上设计实现了CorsBox系统.CorsBox系统采用一种基于目录树的同步方式,在提高安全性的同时保证了共享操作的最终一致性,为用户提供访问权限控制、大数据断点传输、版本控制等功能.测试结果表明,安全机制仅给系统带来了很少的额外开销,说明CorsBox系统在提高数据安全性的同时依然具有良好的性能.
[Abstract]:With the rapid promotion of cloud storage, more and more users begin to use disk system to store data. However, the latest research results show that there are common security vulnerabilities in existing disk systems. In recent years, the network disk leakage of user data events more confirmed the existence of these vulnerabilities. In this paper, a safety net disk system architecture in cloud storage environment is proposed, and a synchronization method based on directory tree is designed and implemented in CorsBox system .CorsBox system. At the same time, it can improve the security and ensure the final consistency of the shared operation, and provide users with access control, big data breakpoint transmission, version control and other functions. The test results show that the security mechanism only brings little extra cost to the system, which indicates that the CorsBox system still has good performance while improving the data security.
