Attribute-based data access control in mobile cloud computing: Taxonomy and open issues

Abstract

With the thriving growth of the cloud computing, the security and privacy concerns of outsourcing data have been increasing dramatically. However, because of delegating the management of data to an untrusted cloud server in data outsourcing process, the data access control has been recognized as a challenging issue in cloud storage systems. One of the preeminent technologies to control data access in cloud computing is Attribute-based Encryption (ABE) as a cryptographic primitive, which establishes the decryption ability on the basis of a user's attributes. This paper provides a comprehensive survey on attribute-based access control schemes and compares each scheme's functionality and charac..
