Trust-Based Secure Workflow Path Construction

—Service-oriented computing promotes collaboration by defining the standards layer that allows compatibility between disparate domains. Workflows, by taking advantage of the serviceoriented framework, provide the necessary tools to harness services in order to tackle complicated problems. As a result, a service is no longer exposed to a small pre-determined homogeneous pool of users; instead it has a large, undefined, and heterogeneous pool of users. This paradigm shift in computing results in increased service exposure. The interactions among the services of a workflow must be carefully evaluated against the security risks associated with them. Classical security problems, such as delegation of rights, conflict of interest, and access control in general, become more complicated due to multiple autonomous security domains and the absence of pre-established trust relationships among the domains. Our work tackles these problems in two aspects: it provides a service owner with the neces...
