Abstract The cloud computing offers dynamically scalable resources provided as a service over the Internet. It promises the drop in capital expenditure. But practically speaking if this is to become reality there are still some challenges which is to be still addressed. Amongst, the main issues are related to security and trust, since the user’s data has to be released to the Cloud and thus leaves the secured area of the data owner. The users must trust the providers. There must be a strong trust relationship exist between the service providers and the users. This paper provides a model based on reputation which allows only reliable providers to provide the computing power and the resources which in turn can provide a reliable infrastructure for cloud computing.

1 Introduction Cloud computing has a lot of common features as Grid computing. It can be argued that the cloud computing has evolved from Grid computing. Grid computing actually provides infrastructure to cloud computing which includes computing and storage resources where as cloud aims at economic based delivering of resources and services. Data Security is of prime importance for any business. A cloud service provider needs to secure its infrastructure, its applications, as well as the stored business data. With cloud computing all the data is stored and processed remotely in another machine. P. Srivaramangai (B) Botho college, 501564 Gaborone, Botswana e-mail: [email protected] R.

The infrastructure that supports the platform from which the user interacts is unseen by the user. The consumer of services fear that the information stored in cloud may be accessed by hackers. The service providers must also expected to be committed to the local privacy policies of the customers. Cloud computing contributes a lot to business world. But still Enterprises have a lot of concerns about the reliability and security of these remote clouds. People are not comfortable with the data being stored under the control of third party provider. There is no assurance that the cloud providers will not go out of business. Reliability is the major concerns of the customers of cloud computing. Cloud computing and its related technologies will only be adopted by users, if they are confident that their data and privacy are secured, and the system is as scalable, robust and reliable as of their own, in their places. Trust and reputation systems have been recognized as playing an important role in decision making on the internet. Reputation based systems can be used in a Grid to improve the reliability of transactions. Rel
