A secure data service mechanism with temporary allow access in mobile cloud computing

To provide privacy and enhance security for mobile cloud users, a few proposals have been presented recently. However we argue that most of them, dont achieve all goals of mobile cloud computing In this paper, we propose a secure data service (DSMCC) an efficient and secure data service mechanism in mobile cloud computing, which enables the mobile users to enjoy a secure outsourced data service at the minimized security management overhead and power consumption. Our protocol is flexible to operate and scalable with the growth of data sharers and Protect the mobile user’s data from leaking to the cloud, also Guarantee the authorized sharers can access the data for time period i, while unauthorized sharers can not learn anything about data, and Reduce the communication cost of mobile user.our analysis show that this scheme has more advantages than other mobile data service mechanism , which could better cater the requirements in mobile cloud computing scenarios
