Effective Data Access Control in Mobile Cloud Computing Using LDSS CP-ABE

Mobile Cloud Computing is an information technology paradigm that enables ubiquitous access to shared pools of configurable system resources provisioned with minimum management effort. Since the personal data is being stored and retrieved from the cloud. Data security problem become an obstacle for further developments. Although substantial studies have been conducted to improve the cloud security, most of them are not applicable for mobile cloud, as these mobile devices are generally less powerful and consume more energy. Solutions in with low computational overhead are in great need. In this paper, we have proposed a lightweight data secure scheme(LDSS) for mobile cloud computing. It adopts the CP-ABE, an access control technology used in normal cloud environment, but changes the structure of access control tree to mobile it suitable for mobile cloud environment. External proxy servers are being introduced for mobile devices to reduce computational overhead. The probing outcome of the scheme LDSS, effectively reduces the overhead on the mobile devices.
