Cloud computing is highly promising technology because of its unlimited resource provisioning and data storage services which help the user in managing the data as per requirements. But this area is still suffering problem of secure storage and communication of data inside the cloud and in between clouds also. Due to the use of internet and vital remote servers to maintain the data and applications, the cloud computing environment becomes open for the attackers to attack on the user data and communication services. This paper mainly focuses on the user authentication and data security over the Broker Cloud Computing Paradigm by exploiting the cryptographic techniques as Selective Encryption using AES.
