Derivation of trust federation for collaborative business processes

Service Oriented Architecture (SOA) is considered to be an important enabler of Internet of Services. By adopting SOA in development, business services can be offered, mediated, and traded as web services, so as to support agile and dynamic business collaborations on the Internet. Business collaboration is often implemented as cross-enterprise processes and involves more than one business entity which agrees to join the collaboration. To enable trustworthy and secure provision of services and service composition across enterprise boundaries, trust between business participants must be established, that is, user identities and access rights must be federated, to support business functions defined in the business processes. This paper proposes an approach which derives trust federation from formally described business process models, such as BPMN and WS-CDL processes, to automate security configuration of business collaborations. The result of the derivation is trust policies which identify trust relationships between business participants and can be enforced in enterprises’ service runtimes with support of a policy deployment infrastructure.
