Abstract: The novel and updated scheme strongly focuses on the data processing, storing and accessing the data which is designed to ensure the users with legal authorities to get corresponding classified data and to restrict the illegal users and unauthorized legal users get access to the data which makes it extremely suitable for the mobile cloud computing. There are different parameters to evaluate the performance of the existing Attribute-Based Encryption (ABE) methods in cloud computing as follows: ciphertext size (communication cost), private key size (storage cost), public key size (required storage to store the public key of authorities in the ABE method), re-keying size (the size of the rekeying message that can be used to recognize the user revocation for each attribute in the ABE system), computation cost on the data owner (required time to encrypt data by a data owner), computation cost on the user (required time to decrypt data by a user). Our research work also analyses the importance of the data security in the cloud. Reason for choosing symmetric encryption algorithms are efficient to handle encryption and decryption for large amount of data and effective speed of storing data and accessing the data in the cloud system. For implementation purpose here are considered the type of file as document file (doc), text file (txt) which can be enhance to sound file, video file, image file with different formats.
