Survey on trust establishment in cloud computing

Cloud computing has recently appear as a promising hosting platform that performs an smart usage of a collection of services, applications, information and infrastructure composed of pools of computer resources for storage with the ability to provide users dynamically scalable, shared resources over the Internet and avoid large forthright fixed costs. However along with these advantages, that is storing of data on the clouds including invaluable information which attracts highly skilled blackhat-hackers thus creating a need for the security to be considered for improving client´s trust over the information and services in cloud computing as one of the critical issues. In this survey paper, we have reviewed trust and security relation and proposed an Distributed Trust Model as per actors and their role which help us for managing trust over the services provided by any cloud. In our study, we found that as in distributed approach is implemented in our mechanism; it brings better quality of service and client response.
