云计算环境下基于信任的访问控制模型研究
Research on Trust-based Access Control Model in Cloud Computing Environment
摘要
Abstract
With extensive application of cloud computing,the research of cloud computing becomes more and more rich,at the same time, various problems also become more and more,and the safety has been a popular one of concern,and its importance is gradually rising trends. Cloud computing security problems include access control,virtualization and Web security. For access control problem in cloud computing environment,introduce the idea of trust management and propose an access control model based on trust. The model calculates user’ s behavior trust value according to the behavior evidences that are obtained in real time,and then determine the appropriate permis-sions depending on the confidence value. When the user has a non-secure access behavior,this model can dynamically adjust the user’ s permissions,effectively preventing users from the non-secure access behavior and protecting other users and important resources in the cloud from destruction. The experimental results show that trust values according to the model are more in line with the user’ s actual situ-ation,and the model can resist malicious attacks of users effectively.关键词
