Workflows are operational business processes. Workfow 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. Therefore, they do not deal with flow control, a very important requirement in WFMS. In this paper, we suggest a decentralized and dynamic approach to handle a security policy in workflows taking into account access and flow control.
