Title of Talk: Security of Things and their Low Cost Authenticated Interaction in the world of IoT

Dr. Debdeep Mukhopadhyay,
Professor, Department of Computer Science and Engineering, IIT-Kharagpur


With the advent of Internet of Things (IoT) the need and challenges of security have increased manifold. While the “things” of the IoT have to be secured against adversaries and are fortified by conventional cryptography, they are the hot beds of the growingly menacing side channel attacks, which target weaknesses in implementations. On the other hand, cost is a major constraint for many of these devices and hence IoT devices are routinely being sold with proprietary authentication and security mechanisms, which can be subverted quite easily. This motivates the study of unconventional secured authentication and key establishment protocols using novel hardware primitives called Physically Unclonable Functions. In this talk, we summarize research directions of Secured Embedded Architecture Laboratory (SEAL), IIT Kharagpur, India in the broad area of hardware security. Subsequently, we present an overview on side channel attacks. These vulnerabilities can be potentially used by skilled adversaries to compromise trusted executions which are considered to be the base of various emerging applications like automotive. Finally, we present an overview on PUFs and their usages in developing low-cost authentication suitable for IoT environments. In particular, we present designs being developed in SEAL using PUF based authentications which can also lead to key establishment without the need of Public-Key-Infrastructures, which are a major bottleneck for IoTs.
