Secure and privacy enhanced authentication framework for cloud computing

Cloud computing is a revolution in information technology. The cloud consumer outsources their sensitive data and personal information to cloud provider´s servers which is not within the same trusted domain of data-owner so most challenging issues arises in cloud are data security users privacy and access control. In this paper we also have proposed a method to achieve fine grained security with combined approach of PGP and Kerberos in cloud computing. The proposed method provides authentication, confidentiality, integrity, and privacy features to Cloud Service Providers and Cloud Users.
