The Dynamic Management Of Trusted Cloud Computing Environment

In cloud computing to businesses and individuals increasingly widely used, butthe reliability and security of cloud computing is an indispensable part. Traditionalsecurity solutions can solve part of the cloud computing security issues. But in thecloud computing environment, there are the cloud-specific security issues. cloudcomputing services cloud security concerns has been a bottleneck restricting thedevelopment of cloud computing. Therefore, the establishment of a trusted cloudcomputing platform has practical significance. In this paper, security issues of cloudcomputing, the use of trusted computing platform to establish a credible chain toensure the credibility of cloud computing while using a trusted third party to providecredible verification and evaluation, system design credible cloud computing services,available to users credible cloud computing services.Firstly, introduction of multi-factor authentication and role-based access controlmulti-tenant of cloud computing resources solve the access replay attacks, insecurityinterfaces and APIs, such as security issues.Secondly, by studying the current trusted computing and cloud computingtechnology achievements, using a trusted cloud computing platform design crediblemechanism. In this paper, considering the physical layer of cloud computing, cloudcomputing platforms in different physical play different roles and assume differentfunctions. Therefore, we mainly consider the local physical node credible verification,validation interaction between different nodes, in order to reach the entire cloudcomputing platform system dependability, and presents a user-mode dynamic credibleverification mechanism. Finally, there is analysis of the effectiveness and cloudcomputing platforms credible performance.In short, we use a trusted cloud computing platform to design credible anddynamic multi-factor authentication to solve the problem of trust in cloud computingand control issues. it has some practical significance in the promotion of cloudcomputing.
