Decentralized access management scheme to the cloud data storage

Abstract

Consideration is given to enhancing storage security and maintaining data access control in cloud storage. Existing ways of controlling such access are analyzed. An enhancement of the encryption technique is proposed, based on the attributes of the ciphertext policy and its application in a decentralized data access management system in multi-user cloud storage systems. The main objective is to improve the security and privacy of the management of the cloud storage for which the existing management does not meet all the necessary requirements.
