Cloud computing has emerged as one of the most influential paradigms in the IT industry in current years. Since this new computing technology requires users to entrust their valuable data to cloud providers, there have been growing security and privacy concerns on outsourced data. Numerous schemes employing Attribute-Based Encryption (ABE) have been proposed for access control of outsourced data in cloud computing. In order to get scalable, flexible, & fine-grained access control of outsourced data in cloud computing, in this paper, the authors propose Hierarchical Attribute-Set-Based Encryption (HASBE) by extending cipher text-policy Attribute-Set-Based Encryption (ASBE) with a hierarchical structure of users.
