Authority Cloud Data Manage and Social Security Using Identity-Based Encryption

Abstract

Cloud computing is a revolutionary computing paradigm which enables flexible, on-demand, and low-cost usage of computing resources, but the data is manage to some cloud servers, and number of privacy concerns emerge from it. New identity based encryption has been proposed to secure the cloud storage and targets the data contents privacy and the access control, while less attention is paid to the privilege control and the identity security. We present a semi anonymous privilege authority scheme to address not only the data privacy, but also the user identity privacy in existing access control schemes also generalizes the new file access control to the privilege authority, which privileges of all operations on the cloud data is managed in a compact structured manner. Subsequently, Anonymity control decentralizes the central authority to bind the identity leakage and so attains semi anonymity. In this model we have proposed an attribute based encryption technique is different from previously encryption techniques. Many of the previously proposed encryption techniques which are used in data sharing scenario have some models like varying size of cipher text, user revocation which are resolved in this model. The privileges of processes on the cloud data is accomplished in a fine-grained manner. Successively the AnonyControl-F is fully prevents the identity leakage and achieves the full anonymity is presented.
