基于动态协商的网格访问控制模型

An access control model based on dynamic negotiating in grid

为解决网格用户访问权限的全局一致性问题,基于NIST RBAC访问控制模型和网格特性,提出一种改进的动态协商访问控制模型,通过访问策略及其动态协商机制,为网格访问控制中用户对资源访问权限的全局一致性定义及自动恢复协同提供支持.测试结果表明该机制是可实现的.

In order to support global consistent access privileges granted grid users,a dynamic negotiating access control model based on NIST RBAC model and grid characters was proposed.The model,embodying access policies and its dynamic negotiating mechanism,supports to define global consistent access privileges and automatically resume consistency when conflict occurrs.The testing shows that the mechanism is implemented and feasible.
