As the popularity of cloud computing increases on mobile devices, this can store or retrieve personal data from anywhere at any time. At the same time, the problem of data security also increases day by day and substantial studies have also been conducted to improve cloud security, but most of them are not applicable to the mobile cloud, since mobile devices they have a very limited capacity and capacityresources. In this we provide a solution through a light data exchange scheme (LDSS) for mobile cloud computing. Adopts CP-ABE, which changes the structure of access control and even access control technology used in normal cloud environments. This scheme moves a large part of the transformation of the CP-ABE intensive computing access control tree from mobile devices to external proxy servers. Attribute description fields are used to implement deferred revocation in order to reduce the cost of user revocation, which is a thorny problem in systems based on CP-ABE programs. When users share data in mobile cloud environments, this LDSS can effectively reduce the overhead on the mobile device side.
