Cloud computing has emerged as one of the most influential paradigms in the IT industry in recent years. Since this new computing technology requires users to entrust their valuable data to cloud providers, there have been increasing security and privacy concerns on outsourced data. Several schemes employing Attribute-Based Encryption (ABE) have been proposed for access control of outsourced data in cloud computing. The proposed scheme is not only achieves scalability due to its hierarchical structure, also inherits flexibility and fine-grained access control in supporting compound attributes of ASBE.
