云存储数据安全关键技术研究

云计算作为未来IT产业的发展方向，其自身安全性是制约发展的核心因素。数据安全和隐私保护是是云安全中的核心考虑问题。本文以云数据的生命周期为脉络，结合提供云服务时可能产生的威胁风险，重点分析了云存储数据安全的关键技术，对云存储数据安全有更深刻的理解，进而对云计算的普遍应用与推广具有一定的指导意义。

Research on Key Technologies on Cloud Storage Data Security

Cloud computing is regarded as the future direction of the development of IT industry, but its own security is a core factor which restricts the process of development. Data security and privacy protection are the most crucial is-sues in cloud security which needs to be considered. In this paper, the life cycle of cloud data is to be the thread of thought and the threat risks occurred likely in cloud services are combined with it;the analysis of key technologies of cloud storage security is focused on. The purpose is to have a deeper understanding of cloud storage data security,thus it has certain guiding significance in the universal application and promotion of cloud computing.
