Cloud has been around for two decades and it consists of the vast amount of data from all over the world. Most of the people at a personal level and organization level have moved their data to the cloud and share data across all around the world. The ubiquity of distributed computing, cell phones can stock and recover sensitive data from cloud whenever. Therefore, the information security issue in versatile cloud tries out to be increasingly extreme and forestalls advance improvement of portable cloud. There are generous examinations that have been run to enhance the cloud security. Be that as it can, a big slice of them are not relevant for versatile cloud since cell phones just have constrained registering assets and power. Arrangements with low computational upstairs are in awesome requirement for versatile cloud applications. In this paper, we proposed a (DSA) for portable distributed computing. It embraces CP-ABE, an entrance control innovation utilized as a part of typical cloud condition, yet changes the construction of access regulator tree to make it reasonable for portable cloud conditions. DSA moves an extensive section of the computational genuine access control tree change in CPABE from mobiles to outside go-between servers. Moreover, to decrease the client repudiation cost, it acquaints quality portrayal fields with execute lethargic disavowal, which is a prickly issue in program based CP-ABE substructure. The exploratory outcomes demonstrate that DSA can successfully lessen the overhead on the cell phone side when clients are sharing information in portable cloud conditions.
