Using Anonymous Authentication Securely Storing Data In To Cloud Through Decentralized Access Control

Abstract

Cloud computing is location that allows users to store the data. Cloud computing is logically developed technology to store data from more than one user. In decentralized access control data is stored securely in cloud and here only valid users are able to decrypt the data stored in cloud and this is added feature of this scheme. This scheme supports anonymous authentication. It also supports construction, variation and reading data stored in cloud and also deals with user revocation. This access control scheme is decentralized and robust which is different from other access control scheme and costs are equivalent to centralized approaches.
