云计算环境下任务行为访问控制模型研究
Research on Task Action Access Control Model in Cloud Computing Environment
摘要
Abstract
In recent years,the access control mechanism in cloud computing environment has become a hot topic of research.Since the traditional access control model cannot address the issue of malicious access or processing of cloud system resources by illegal users,based on the traditional access control,the strategy and authorization mechanism of Action Based Access Control ( ABAC) model are studied,and considering the advantages and disadvantages of the ABAC model,a user trust model is introduced,a formal definition of the model as well as the trust similarity algorithm are given,a permission mechanism based trust similarity is designed,and a Task⁃action Based Access Control ( TABAC) model is proposed. The safety and performance analysis shows that this scheme makes access control flexible and reliable,which has a wider application range.关键词
