Survey Paper on User Anonymous Authentication Scheme for Decentralized Access Control in Clouds
Afsha Pathan | M. D. Ingle 
Abstract: The idea is to propose a new decentralized access control scheme for achieving security in data stored in clouds that supports anonymous authentication. In the proposed scheme, the cloud verifies the authenticity of the series without knowing the users identity before storing data in cloud. Here we also have added feature of access control so that only valid users are able to decrypt the data i. e. stored in cloud. The proposed scheme also prevents replay attacks and supports alteration of data and reading data stored in the cloud. We also address user revocation. Moreover, the proposed authentication and access control scheme is decentralized and robust, unlike the existing access control schemes that are centralized. So that here communication, computation, and storage overheads are comparable to centralized approaches.
