Clouds are been extensively used to store sensitive data. It is important that authorized users have access to stored data and unauthorized are not. Fine grained access control means granting selective access rights to selected users. I will talk about fine grained access control in clouds with and without privacy preservation. All the protocols are based on a cryptographic primitive known as Attribute-Based-Encryption. I will discuss various applications along the way and end with cloud access control for resource constrained mobile devices.
