摘要:

在云计算飞速发展的同时,云计算安全也得到了很多关注。云安全联盟指出的云计算面临的风险,主要包括数据中心安全、事件响应、应用程序安全、密钥管理、认证和访问控制、虚拟化层安全以及灾备和业务一致性等。由于云计算和传统IT服务的不同,云计算服务提供商必须通过向用户证明其服务的安全性来获取用户的信任,因此云计算本身是一个可信计算模型,而增加服务透明度则是一项云计算服务提供商应当采取的基本措施。文章提出了一种可信云计算中的多级管理机制,使用该机制能够有效提高云计算服务的透明度,从而使用户可以参与到对自己的服务和数据的管理中,进而提高用户对云计算服务的信心;同时该机制也可以有效降低云服务提供商的运维负担。

Abstract:

More and more attentions are paid to security issues in cloud computing with the rapid development of cloud computing. The CSA (Cloud Security Alliance) pointed out that the risks of Cloud computing, mainly includes data center security and incident response, application security, key management, authentication and access control, the virtualization layer security, and disaster preparedness and business consistency, etc. There are a lot of differences between cloud computing and traditional IT services, so cloud computing service providers must gain the trust from clients by providing the safety of the service provided by them. Hence, cloud computing is constitutionally a trusted computing model. And it would be a fundamental approach to enhance the transparency of the service. This paper proposes a multi-level management mechanism for intrusted cloud computing. This mechanism is able to enhance the transparency of cloud computing so that the clients can get involved into the management of their own data and services. Meanwhile, this mechanism would improve the confidence of clients for the cloud computing service and reduce the operation and maintenance overhead of the cloud service provider.

Key words: trusted computing, cloud computing, multi-level management, trusted cloud
