Reputation and attribute based dynamic access control framework in cloud computing environment for privacy protection

摘要

A Reputation and Attribute Based Dynamic Access Control (RA-DAC) Framework for Privacy Protection in Cloud Computing Environment was presented in this paper. First, RA-DAC is used to encourage honest users for their good actions in cloud environment. Second, RA-DAC is also used to constraint malicious users for their destructive actions in cloud environment. And finally, based on RA-DAC we developed the Reputation and Attribute Based Dynamic Access Control System (RA-DACS) which is used to detect the malicious behaviors of dishonest users and automatically prevent their further action to threaten the security of the cloud computing environment.
