Attribute Based Encryption with Privacy Protection in Clouds

Abstract

I propose 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 user without knowing the user’s identity before storing data. Decentralized scheme also has the added feature of access control in which only valid users are able to decrypt the stored information. This scheme prevents replay attacks and supports creation, modification, and reading data stored in the cloud and also address user revocation. Moreover, this 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.
