云计算中数据存储安全的研究

The Research of Data Storage Security in Cloud Computing

云计算作为IT发展的下一阶段,尽管有很多的优势,如提高业务的灵活性、可扩展性、工作效率以及企业的盈利能力,但是在带来这些优势的同时也带来云计算新的安全风险和问题。在众多的安全问题中,数据的存储安全已经成为云计算安全的核心问题。针对云计算数据的特点,在对数据加密技术研究的基础之上,本文讨论数据的敏感性问题,结合数据加密方法的优点,提出将数据分为不同安全级别然后结合密码技术,从而达到数据的在云计算环境下安全存储的方案。

As the next stage of IT development, Cloud computing is causing everyone＇s attention. While cloud computing has many advantages, such as improved business agility, scalability, efficiency and profitability of the enterprise, it also brings a new security risks and problems of cloud computing. However, in many of the securi- ty problems, the data storage security has become a core problem in cloud computing security. For Characteris- tics of the data for cloud computing, data encryption technology on the basis of research, the paper, which dis- cusses the problem of sensitivity of the data, combined with the advantages of data encryption method, was pro- posed to classify data into different security levels and then with the best encryption technology so as to achieve the security of data storage solution.
