Workflows are operational business processes. Workflow Management Systems (WFMS) are concerned
with the control and coordination of these workflows.
In recent years, there has been a trend to integrate
WFMS in distributed inter-organizational systems.
In this case malfunctioning of one WFMS can affect
more than one organization, making the correct functioning of a WFMS a critical issue. Thus, an important function of WFMS is to enforce the security
of these inter-organizational workflows. Several works
have been done to integrate the security aspects in the
workflow specification. Unfortunately, these research
works generally adopt a centralized management approach and are based on static access control models.
In this paper, we suggest a decentralized and dynamic
approach to handle access control in workflows.
