An Proficient Presentation of Attribute Based EncryptionScheme in CloudComputing

Abstract

Cloud computing is oneof the up-coming technologies used for handling voluminous data and its storage.In this paper, we present a semianonymous privilegecontrol scheme AnonyControl to address not only the dataprivacy, but also the user identity privacy in existing accesscontrol schemes. AnonyControl decentralizes the centralauthority to bound the identity leakage and thus achievessemianonymity. In addition, it also generalizes the file access controlto the privilege control, by which privileges of all operations onthe cloud data can be managed in a fine-grained manner.Consequently, we present the AnonyControl-F, which fullyprevents the identity leakage and achieve the full anonymity.
