Abstract: With the advent of Internet of Things (IoT) the need and challenges of security have increased manifold. Starting from the miniature devices, which are often resource constrained, to the pervasive omni-present cloud, all avenues for a potential attack need to be mitigated. In this talk, we discuss the research activities in this direction, starting from physical security of the “things” in an IoT framework to developing dedicated cryptographic techniques for delegating data in the cloud. The talk also summarizes the research activities at the Secured Embedded Architecture Laboratory (SEAL), IIT Kharagpur, India.

We conclude with a discussion on such Key Aggregate Cryptosystems (KAC), which provides an efficient solution to allow users to decrypt multiple classes of data using a single key of constant size that can be broadcast to multiple users. SEAL attempts to develop parallel hardware architectures for such access mechanisms, and extend it to handle functionalities, like search in a controlled manner, over encrypted data generated by billions of devices in the IoT.
