云计算差异化安全技术研究

Study on Differentiated Security Service Based on Cloud Computing

云计算的部署和应用可以明显节约IT成本,促进业务的创新和发展,然而公有云将用户数据和业务处理环节交由独立第三方提供,使用户数据和业务系统面临更多的安全威胁,安全已经成为云计算发展的主要瓶颈。本文根据用户对云业务多样化的安全需求,提出差异化安全技术框架,在满足用户安全要求的前提下,降低安全对云计算计算资源的消耗,从而促进云计算的应用。

Deployment and application of cloud computing can significantly save computing resource, and promote business innovation and development. However, if users＇ data is stored and processed in public cloud computing which is provided by an independent third party, more security threat will be faced than that of the traditional way. Security has become one of the most important obstacles for the development of cloud computing. Differentiated security architecture was proposed, according to the diversity of security requirements from different users. The consumption of computing resource from security service could be reduced and thus the development of cloud computing is benefited.
