Abstract

Virtual Enterprise has features of distribution and dynamic, which bring some problems of information security. It is an important research subject for access control of data in virtual enterprise workflow management system. Based the traditional ORBAC (organization and role based access control) model, the authorization strategy is introduced to realize synchronization between authorization flow and workflow. It presents the types of authorization constraint and collision detecting rules avoiding the execution-interruption problem brought by constraint collision.
