Generic attribute revocation systems for attribute-based encryption in cloud storage

Genlang Chen, Zhiqian Xu, Jia-jian Zhang, Guojun Wang, Hai Jiang, Miao-qing Huang

Abstract

Attribute-based encryption (ABE) has been a preferred encryption technology to solve the problems of data protection and access control, especially when the cloud storage is provided by third-party service providers. ABE can put data access under control at each data item level. However, ABE schemes have practical limitations on dynamic attribute revocation. We propose a generic attribute revocation system for ABE with user privacy protection. The attribute revocation ABE (AR-ABE) system can work with any type of ABE scheme to dynamically revoke any number of attributes.
