摘要: 安全方便地获取共享信息资源是虚拟企业成功的关键因素。该文分析了一个虚拟企业访问控制的基本要求,提出一个虚拟企业访问控制模型,该模型由管理公共资源的基于项目的访问控制和管理私有资源的基于角色的访问控制这2个子模型构成。给出了该模型的组成和系统结构,实现了虚拟企业之间的资源管理和共享。

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)
