Abstract
In this paper we identify specific security requirements for distributed workflows and provide a decentralized workflow execution mechanism that ensures their satisfaction. With our composition concept we ensure that each web service can access only the information which is needed for the correct execution of the invoked operations and we provide an execution proof of the fulfilled assignments. Our approach relies on a data structure, called process slip, which is passed among the web services participating in the composition.
