Study of Controlling Cloud Data Access Privilege and Attribute Based Data Sharing with Attribute Revocation

2015 International Journal of Science and Research (IJSR)  
Cloud computing is a revolutionary computing environment, which allows user a flexible, on-demand, and low-cost usage of computing resources, but as the data is outsourced to some cloud servers, and various privacy issues emerge from it. To handle these security problems, various schemes based on the Attribute-Based Encryption have been proposed recently. Attribute-based Encryption (ABE) is a cryptographic conducting tool to guarantee data owner's direct control over their data in public cloud

ABE is a public-key based one to many encryption methodologies which allows users to encrypt and decrypt data based on user attributes. In this paper we studied various schemes of ABE like KP-ABE, CP-ABE, Anony Control and Anony Control-F, also we analyzed how data access privilege and data sharing can be controlled by using various schemes of ABE.
