Currently, cloud computing is ubiquitous as the IT deployment resource in networks. Conversely, there are some critical issues in cloud security. One of the significant concerns in cloud security is user access control. As user's data is processed somewhere at a remote place, the user has concerns about the confidentiality of their data. The paper proposes a new model by federating authentication, authorization and auditing with cryptography. The owner of the data encrypts the data prior to uploading the data in cloud.
