A Novel Cloud Data Storage Mechanism to Enhance Communication and Transaction Security for Concurrent Users

Abstract

ABSTRACT newlineCloud computing is a most alluring technology that facilitates conducive, on-demand network access based on the requirement of users with nominal effort on management and interaction among cloud providers. The cloud storage serves as a dependable platform for long term storage needs which enables the users to move the data to the cloud in a rapid and secure manner. It assists the companies and government agencies to considerably decrease their economic overhead of data organization, as they can store their data endorsement vaguely to third-party cloud storage sources than preserving the data centers on their personal devices. It also allow users to accumulate their data at a remote location and have the on-demand high superiority cloud requests without the burden of restricted hardware and software organization. newlineAlthough the profits are obvious, such a service is also turning down user s corporeal control of their outsourced data, which unavoidably facades novel security dangers towards the accuracy of the data in cloud. Several schemes have been provided in cloud computing for enhancing the security, however most of them sustain from leakage of data. This leads to a greater issue while sharing the data in the cloud computing environment. Moreover, the transaction of cloud data is performed by different users at diverse access levels. The cloud data storage does not focus on maximizing the security on performing the transactions over cloud servers. Furthermore, signified by the expanding arrival rate of cloud users, though many works have concentrated on distributed accountability during data sharing and performing audit services, the cloud applications pose a great challenge in addressing data consistency. The data consistency state needs to be handled effectively for improving the communication cost and computation users of the cloud. newlineIn order to realize the leakage of data in the cloud, an Instant Communication Channel Key Organizer (ICCKO) model was constructed which supports the security and data co
