Trust Model for Computing Security of Cloud

In this technological era, computing security of the cloud is a major concern viz, Trust Model for computing security of cloud is an attractive area of research. In the era of the cloud environment, it is very difficult to choose right service provider because each provider has their own services, which has various features, policies, and provisions. Different technologies are used by service providers for achieving security. A cloud user always needs to take a decision of selecting the service out of various available options. It is based on requirements of user and intensity of protection provided by available service. It is really very difficult for the user to compare the services available and choose one based on security parameter. In this paper, authors are trying to overcome this challenge by developing a trust model for the computing power of a cloud service with respect to its security. Here for providing various aspects of security like authorization and authentication, the trust value is generated using implemented trust model. This paper focuses on various parameters like the safety of data, individuality management (uniqueness of user), authorization, authentication, and virtualization to provide security to the cloud. The model implemented here can be used by users of the cloud for assessment of various cloud services. It becomes easy for the user to find faithful service. Also, this model helps the cloud service provider for finding weaknesses and enhancement in their services. Cloud Service providers are able to use this as a security strength evaluation tool for various cloud services.
