In cloud, transactional database provides authorization, it is one of most important for proof of authorization, it I the base for performance evaluation. In this paper, the authors are concentrating on mainly on three concepts i.e. one is the authorization of users in the cloud. For this they are using concept of digital signature for user authentication. Second one id for accuracy of each transaction, they implemented group key protocol for sharing of data in the cloud. Third one is security of cloud transaction they are AES algorithm for encryption and decryption of cloud transaction.
