Design and Implementation of User Anonymity and Authentication Scheme for Decentralized Access Control in Clouds: Review

Pooja R. Vyawhare | Namrata D. Ghuse [4]

Abstract: Placing critical data in the hands of a cloud provider should come with the guarantee of security and availability for data at rest, in motion, and in use. Several alternatives exist for storage services, while data confidentiality solutions for the database as a service paradigm are still immature. To protect outsourced data in cloud storage against corruptions, adding fault tolerance to cloud storage, along with efficient data integrity checking and recovery procedures, becomes critical. So, this work proposes a new decentralized access control scheme for secure data storage in clouds, which supports anonymous authentication. In the proposed scheme, the cloud verifies the authenticity of the ser without knowing the users identity before storing data. Our scheme also has the added feature of access control in which only valid users are able to decrypt the stored information. The scheme prevents replay attacks and supports creation, modification, and reading data stored in the cloud. We also address user revocation. Moreover, our authentication and access control scheme is decentralized and robust, unlike other access control schemes designed for clouds which are centralized. The communication, computation, and storage overheads are comparable to centralized approaches.
