Cloud Privilege of Access to Data and Anonymity with the Unknown Entirely Based Encryption to Control Characteristics

Abstract

Cloud computing is a model revolutionary computing, which enables flexible, on-demand, low-cost and use of computing resources, but outsourcing data sources to some cloud servers, and concerns about the privacy of different out of it. Various schemes have been proposed based on the existing encryption feature to secure cloud storage. However, most of the work on the privacy of the contents of the data and access control, while focusing less attention is being given to the control of the franchise and privacy of identity. In this paper, we provide semi-anonymous control scheme AnonyControl privilege to address not only on data privacy, but also the privacy of the user's identity in the access control list systems. Decentralizes AnonyControl central authority to limit the leakage of identity and thus achieves semianonymity. Besides, it also circulates in the file control access to the control of a franchise, which privileges to all processes on the cloud data can be managed through a fine-grained. Later, we offer AnonyControl-F, which completely prevents the leakage of identity and achieve non-disclosure of his full name. Our security analysis shows that both AnonyControl and AnonyControl-F is safe under the coherent decision Diffie-Hellman assumption, and evaluate the performance of our exhibits feasibility of our plans
