With computer operations and mobile device technologies expanding, mobile cloud computing has been shaping up as the future of web-based communications. Data security has consistently been a major issue which restricts the further development in mobile cloud. Many measures have been undertaken to improve in cloud computing. As the mobile devices have finite resource and power most of the studies on cloud computing are not convenient on mobile devices. Hence it becomes requisite to diminish the computational overhead in mobile cloud computing. In this paper we come up with a scheme called as light weight data secure sharing scheme for mobile cloud. It embraces CP-ABE which is one of the most suitable technologies for data access control in cloud storage system but alters the framework of access control tree to make it appropriate for mobile cloud environments. External proxy servers are being introduced to reduce the computational overhead on mobile device. Attribute description fields are used to implement lazy revocation which depletes the user revocation cost. The investigational outcome unveils that LDSS is capable to decrease the overhead issues on the mobile device when the data is being shared in mobile cloud environment.
