云计算环境数据安全研究

Research on Data Security in Cloud Computing

云计算是网格计算、分布式计算、效用计算等技术发展融合的产物,如今普及速度非常快。亚马逊、谷歌、微软等企业向用户提供了在云环境中开发应用和远程访问应用的功能。由于云环境的数据托管给服务商存储在远程服务器中,且应用数据通过互联网传输,数据存储和传输安全是一个重要的问题。在实现云计算之前,首先应该解决由此带来的安全问题。论文描述了云计算中数据安全相关的挑战,研究了对于数据安全不同层面的解决方案。

Cloud computing is the product of the integration of the technology development of grid computing, distributed computing, utility computing,and this trend is rapidly increasing. Amazon, Google, Microsoft and other enterprise have provided users with the function of the application and remote access in the cloud environment. As data in the cloud environment is stored in remote server, and the application of data is transmitted through the Internet,data storage and transmission security is an important issue. Before apply cloud computing, we should first address related security issues. This paper describes the chal enges of data security in cloud computing, and studies the solutions for different levels of data security.
