Decentralizes the central authorities in Cloud for Data Access Control

Abstract

Cloud computing is an innovative processing paradigm, which allows flexible, and low cost utilization of computing methods, nevertheless the data is outsourced for some cloud, and various privacy security concerns arise from it. Various plans based on the attribute-based encryption have been recommended to secure the cloud hosting storage. However, most jobs focuses on the information contents privacy and the access control, while significantly less attention is paid to the privilege control as well as the identity privacy. In this paper, semi anonymous privilege control system is introduced; here AnonyControl is to address certainly not only the data personal privacy of privateers, but also individual identification privacy. AnonyControl decentralizes the central authorities to limit the identity leakage and therefore achieves semi anonymity. Besides, it also generalizes the file access control towards the privilege control, by which usually privileges of all functions on the cloud information can be managed within just a fine-grained manner. Therefore this paper presents the AnonyControl-F, which fully prevents the identification leakage and obtains the complete anonymity.
