Cloud storage is simple and scalable way to store, access and share data over the Internet. Consequently, data security problems are becoming more and more severe and prevent further development of mobile cloud. There are several studies that have been done to improve the cloud security. However, most of them are not applicable for mobile cloud since mobile devices have less computing resource and power. Solution with low computational overhead is in great need for mobile cloud applications. In this paper, we propose a Lightweight data sharing scheme (LDSS) for mobile cloud computing. It adopts Cipher Policy- Attribute Based Encryption (CP-ABE), an access control technology used in normal environments, but it changes the structure of access control tree to make it suitable for mobile cloud computing. LDSS moves large portion of the computational intensive access control tree transformation in CP-ABE from mobile devices to external proxy servers. Attribute based encryption (ABE) is used to for cloud storage security.
