Analysis verifies that the model can ensure that users access cloud services anonymously and that cloud providers assess the credibility of users effectively without violating user privacy. ...
To solve these problems, we introduce a reputation mechanism and design a reputation-based identity management model for cloud computing. ...
Also, we assume that the IdP and CSP can collude together to compromise anonymity. These assumptions comply with the actual situation, for the IdP and CSP may belong to the same institution. ...
