Study of lightweight ABE for cloud based IoT

Cloud computing has made possible that resources are available when needed and on-demand. Cloud computing is used to access and store data on remote servers using internet. Storing data in remote cloud servers leads to privacy and security issues. Attribute based encryption is used extensively for access control in cloud. There has been an upsurge in the IoT devices and IoT devices have been using cloud for data storage. When IoT and cloud converge there is need for newer, lightweight and efficient access control techniques for cloud based IoT, as the IoT devices are resource constrained, and may not be able to support the access control techniques currently used. It is observed that, there is need for lightweight Attribute based encryption (ABE) technique for cloud based IoT.
