摘要
论文分析大数据的特点及体系架构,得出大数据环境下访问控制应满足的原则,即自主、动态、细粒度、跨域授权。通过对比分析访问控制模型DAC、MAC、RBAC及ABAC在大数据环境下适用性,得出结论:ABAC模型最适合应用于大数据。同时,论文针对大数据特性对各模型提出改进建议。
This paper analyzes the characteristics and architecture of Big Data.The Conclusion shows that Big Data need an independent,dynamic, fine-grained,cross-domain access control model.The applicability of DAC, MAC, RBAC, ABAC in Big Data environment has been comparingly analyzed.The Conclusion shows that ABAC is the most applicable access control model for Big Data.The suggestions of making improvements to adapt to the Big Data features have been proposed for access control models.
