Title: Anonymous Authentication of Data Stored in Clouds with Scattered Security Technique
Abstract: Of late the term that creating hype in the IT industry is the Cloud Computing. Inspired and Motivated by the tremendous growth and the huge success of cloud, we propose a new decentralized access control scheme for secure data storage in clouds that supports anonymous authentication. In the proposed scheme, the cloud verifies the authenticity of the series without knowing the user’s 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.
