【摘要】 为使维护联盟中的知识资源能够在权限的约束下共享,结合基于上下文的安全管理和知识管理技术,提出了基于维护业务上下文的访问控制(MBCBAC)模型。与传统的基于角色的访问控制(RBAC)模型相比,MBCBAC模型以维护业务上下文作为访问控制的授权中介来实现业务驱动的知识安全管理,通过维护知识空间来实现知识对象粒度上的访问控制。基于MBCBAC模型构建的知识安全管理组件已成功应用于某e-维护联盟的知识管理系统中。更多还原

【Abstract】 To realize knowledge sharing under authority constraints in plant maintenance federation,a maintenance-business-context based access control(MBCBAC) model was proposed based upon context-based security management and context-based knowledge management technology.Comparing with role-based access control(RBAC) model,the proposed model used "maintenance business context"as the intermediary for authorization to realize business-driven knowledge security management,and adopted maintenance knowledge space to realize access control of knowledge-object level.A component of knowledge security management according to the proposed model had been successfully applied to the knowledge management system for some maintenance federations.更多还原
