Cloud file storage requires users to entrust their valuable data to cloud providers. With respect to increasing security and privacy concerns on outsourced data in clouds, earlier several schemes employing Attribute-Based Encryption (ABE) have been proposed for access control of outsourced data in cloud computing; Later due to their inflexibility in implementing complex access control policies and to realize scalable, flexible, and fine-grained access control of outsourced data in cloud computing, Hierarchical Attribute-Set-Based Encryption (HASBE) with a hierarchical structure of users was developed.
