Workflow Management Systems (WFMSs) provide an automated framework for managing intra- and inter-enterprise business processes. Workfolw is a critical enabler in today's hot technologies, such as portals and e-business. This paper describes the design of a model as well as architecture to provide support for distributed advanced workflow transactions. We discuss the application of transaction concepts to activities that involve the integrated execution of multiple tasks over different processes. These kinds of applications are described as transactional workflows. A distinguishing feature of the workflow transaction support system proposed is the ability to manage the arbitrary distribution of business processes overmultiple workflow management systems. We choose to develop a formal framework for a secure distributed workflow architecture since interworkflow is anticipated as a major supporting mechanism for Business-to-Business Electronic Commerce. We strive to develop a practical logical characterisation of multilevel secure (MLS) distributed workflow for the first time using the inherently difficult concept of non-monotonic reasoning.
