Abstract :
Workflows in the physical world are implemented based on forms printed on paper and signed by the involved people. In contrast workflows in service oriented architectures require a central entity for execution that results in an inflexible system design that is not suitable for ambient environments. Based on an ambient environment example a security approach for decentralized workflows is presented providing authenticity, confidentiality, and non-repudiation for distributed workflow execution.
