Trust Model Engines in Cloud Computing

The first concern when we think about adopting cloud computing is security. Even if, cloud computing seems to be remarkably cheap, the security part might transform the "buzz world" in a terribly expensive technology. The goal of this paper is to present a different perspective of delivering security as a service thru a new defined concept, trust engines. This concept, introduced in this paper, relies on trust management. A trust management system can be achieved in cloud computing by implementing multiple trust models that define what a user can do and what type of protection he has. By identifying the static and dynamic trust models, the cloud provider and the cloud user can have a proper control of the cloud security. A trust model engine could create both static and dynamic rules that will establish a classified profile for all the cloud users.
