the development of cloud computing, mobile devices can store/retrieve personal data from anywhere at any time.as a consequence of the data security problem in mobile cloud becomes more and more severe and prevents further development of mobile cloud. There are substantial studies that have been conducted to improve the cloud security. the most of them are not fit for mobile cloud first mobile devices only have limited computing resources and power. Solutions with low computational overhead are in great need for mobile cloud applications. In this paper, we propose a lightweight data sharing scheme (LDSS) for mobile cloud computing. It depends on CP-ABE, an access control technology used in normal cloud environment, but changes the structure of access control tree to make it suitable for mobile cloud in the context. In addition KP-ABE is implemented in TA to ensure attribute based key encryption and decryption from user. The combination of CP and KP ABE attain better performance compared to existing approaches.
