dc.description.abstractAlotaibi, Ahad Saad (M.S, Computer science) Towards Community Cloud Trustworthiness Thesis directed by Associate Professor Edward Chow. In this thesis we presented an authorization system for community cloud. We investigated the use of XACML rule for specifying the resource access control and explored the use of OpenAM for its implementation. We also investigated how the ranking information of the new community member can be computed based on the recommended rank values of the selected recommending community members with additional weights based on the ranks of the recommenders. We suggest the use of contribution effort and credibility information to revise the ranking periodically The ccAuth system was implemented as a web application in ASP.net connected to MySQL database to test the proposed design. For the performance we test our servers on the three different configurations: baseline, normal operation on a local server, and that with AWS cloud virtual machine at Oregon region. The results show the maximum time performance with the AWS cloud server is 365 milliseconds, well within 1 seconds, and should be considered as acceptable for most applications.
