Cloud Computing Security: Architecture, Mechanism and Modeling

With the wide use of cloud computing services, tenants require higher and higher security assurance. The characteristicsof cloud computing are dynamics, randomness, complexity and openness, which make the original security solutions difficult to beapplied to the cloud environment, so this is a big obstacle to the development of cloud computing. We analyze the features and security challenges of cloud computing, and do a survey on security architecture, mechanism and model. In this paper, we show that thesecurity architecture of cloud computing needs not only the security of many kinds of trusted services, but also the security evaluation of the management and can be controlled.
