Cloud Based Secure and Privacy Enhanced Authentication & Authorization Protocol

Cloud computing is an emerging computing model which facilitates organizations and the IT industry. It helps them to multiply or lessen their resources according to their operational requirements. However, the organizations are reluctant to store their sensitive information on the cloud due to various privacy and identity tracking threats. In the past few years, a lot of research and development efforts have been made to define centralized and federated security mechanisms for the protection of identity information in a cloud environment. However, to the best of our knowledge none of the systems have been designed keeping anonymity as the key component. This paper describes an authentication and authorization protocol which outlines the main features of anonymous communication in the cloud. The solution is an extension of existing standards making it easy to integrate and compatible with existing standards.
