Abstract

Information flow control consists of planning the interactions of composed services in order to satisfy different security restrictions concerning the propagation of information in a composition. We present the design and implementation of a decentralized workflow management solution for the control of information flow. Our contribution targets orchestration-based compositions where centralized workflow descriptions are used to derive distributed and cooperating process fragments. The derived process fragments are deployed on composed services and they enable them to establish P2P interconnections with each other with respect to the information flow policies.
