一种面向云计算环境的属性访问控制模型OA北大核心CSCDCSTPCD
Attribute-based access control model for cloud computing
针对云计算环境下的访问控制问题，结合云计算环境存在多个逻辑安全域的特点，提出一种面向云计算环境的属性访问控制模型。该模型采用基于属性的访问控制方法实现本地域和跨域访问决策。对该模型进行形式化描述并给出决策核心算法。在域间属性同步方面，设计一种信号量及P/V操作机制以解决对属性表调用和更新的互斥问题。仿真实验表明：该模型不仅实现细粒度访问控制，而且能够缩短访问控制决策时间，提高决策效率。
A cloud computing attributes-based access control(CC-ABAC) model was proposed to solve the multi-domains access control problem in cloud computing. An attribute-based access control method was utilized to realize the local-domain and cross-domain access decisions in this model. The formal description of model and core decision algorithm were given. A semaphore and P/V operation mechanism was designed to solve the incompatible problem of call and update the a…查看全部>>
