摘要

提出了一种云计算环境中基于角色的访问控制模型CARBAC

将角色分为用户角色和资源拥有者管理角色。针对管理角色对用户访问的角色指派

提出了在混杂角色层次关系中基于用户权限的角色查找算法。对于一组给定的授权

该算法能在云计算系统的角色中选择一组数量最少的角色指派给用户。仿真实验表明

针对云计算环境中的海量用户访问

本算法能显著减少系统中角色的数量

缩短用户授权时间

提高系统运行效率。

Abstract

Roles based access control model CARBAC for cloud computing environment was proposed.Roles in the model include user roles and resources owner roles

the latter were called administrator roles.For the resources owner roles assigning the roles to the users

roles query algorithm in the hybrid hierarchies based on users’ access require was proposed.Through this algorithm

for the certain privileges set

this model could choose the least roles set to be assigned to the users.The simulation experiment indicates that for the mass user access

this algorithm can reduce the roles quan-tity

shorten the authorization procedure

and advance the system efficiency.
