Now a day’s Mobile cloud storage is most popular in the storage and Exchange of the Data .in the paper to identify, investigate and address the synchronization inadequacy problem of current mobile cloud storage services. In the Existing Synchronization, it fails to the available bandwidth. It generated a large amount of data. It unwanted data is Synchronization to create traffic. We implement the Quick Synchronization of the data using three different technique used to improve the Synchronization efficiency to any other services and its improve the performance of the Synchronization time to the system. Data is generating day by day in cloud computing data is saved on the cloud. So here we have to combine mobile computing with cloud computing so that we can handle the mobile-based application with the cloud platform. So when we store our data on the cloud. Here the existing commercial system fails to compose full use of obtainable Bandwidth and generate a large amount of superfluous traffic. It happens because of the inbuilt restrictions of the sync set of rules and the distributed architecture. The probable of selectively distribution encrypted data with dissimilar users via public cloud storage may seriously ease protection concerns over involuntary data leaks in the cloud. A key confronts to underhanded such encryption schemes trickery in the skillful administration of encryption keys. The favored limberness of distribution any group of preferred identification with any group of users demands different encryption keys to be used for dissimilar documents. However, this also entails the indispensable of self-assuredly distributing to users a large numeral of keys for both encryption and search, and those users will have to strongly store the conventional keys, and submit a uniformly large number of keyword trapdoors to the cloud in categorize to carry out appear for over the communal data. The roundabout needs for a sheltered announcement, storage, and complication undoubtedly render the move toward unworkable. In this paper, we take in hand this sensible predicament, which is largely abandoned in journalism; by proposing the novel concept of key-aggregation.
