Control Cloud Data Access Privilege and Anonymity With Fully Anonymous Attribute-Based Encryption

Abstract— Control Cloud Data Access Privilege and Anonymity With Fully Anonymous Attribute-Based Encryption. Cloud computing is a revolutionary computing paradigm, which enables flexible, on-demand, and low-cost usage of computing resources, but the data is outsourced to some cloud servers, and various privacy concerns emerge from it. < Final Year Projects 2016 > Various schemes based on the attribute-based encryption have been proposed to secure the cloud storage. However, most work focuses on the data contents privacy and the access control, while less attention is paid to the privilege control and the identity privacy. We present a semianonymous privilege control scheme AnonyControl to address not only the data privacy, but also the user identity privacy in existing access control schemes. AnonyControl decentralizes the central authority to limit the identity leakage and thus achieves semianonymity.
