Enforcing access control in composite services is essential in distributed multidomain environment. Many advanced access control models have been developed to secure web services at execution time. However, they do not consider access control validation at composition time, resulting in high execution-time failure rate of composite services due to access control violations. Performing composition-time...
Ensuring secure information flow is a critical task for service composition in multi-domain systems. Research in security-aware service composition provides some preliminary solutions to this problem, but there are still issues to be addressed. In this paper, we develop a service composition mechanism specifically focusing on the secure information flow control issues. We first introduce a general...
