Abstract: Secure information sharing is one of key factors for success of virtual enterprise (VE). This paper analyzes the requirements of a VE access control. A virtual enterprise access control (VEAC) model is proposed to handle resource management and sharing across each participating enterprise, which consists of a project-based access control (PBAC) sub-model to manage public resources and a role-based access control (RBAC) sub-model to manage private resources. The system architecture and constitution of the model are explained. Result implements more secure resource sharing and resource management in VE.

Key words: virtual enterprise(VE), role-based access control (RBAC), virtual enterprise access control(VEAC)
