Workshop on Nano Security: From Nano-Electronics to Secure Systems (NanoSec’23)

April 18, 2023, Antwerp, co-located with Design Automation and Test in Europe (DATE) Conference

Workshop on Nano Security: From Nano-Electronics to Secure Systems (NanoSec’23)

Workshop Scope

Today’s societies critically depend on electronic systems. Security of such systems are facing completely new challenges due to the ongoing transition to radically new types of nano-electronic devices, such as memristors, spintronics, or carbon nanotubes. The use of such emerging nano-technologies is inevitable to address the essential needs related to energy efficiency, computing power and performance. Therefore, the entire industry are switching to emerging nano-electronics alongside scaled CMOS technologies in heterogeneous integrated systems. These technologies come with new properties and also facilitate the development of radically different computer architectures.

The proposed workshop will bring together researchers from hardware-oriented security and from emerging hardware technology. It will explore the potential of new technologies and architectures to provide new opportunities for achieving security targets, but it will also raise questions about their vulnerabilities to new types of hardware-oriented attacks. The workshop is based on a Priority Program funded since 2019 by the German DFG, and will be open to members and non-members of that Priority Program alike.

Securing the Internet of Bodies using Human Body as a ‘Wire’
Shreyas Sen, Purdue University

Abstract: Radiative communication using electromagnetic (EM) fields is the state-of-the-art for connecting wearable and implantable devices enabling prime applications in the fields of connected healthcare, electroceuticals, neuroscience, augmented and virtual reality (AR/VR) and human-computer interaction (HCI), forming a subset of the Internet of Things called the Internet of body (IoB). However, owing to such radiative nature of the traditional wireless communication, EM signals propagate in all directions, inadvertently allowing an eavesdropper to intercept the information. Moreover, since only a fraction of the energy is picked up by the intended device, and the need for high carrier frequency compared to information content, wireless communication tends to suffer from poor energy-efficiency (>nJ/bit). Noting that all IoB devices share a common medium, i.e., the human body, using the conductivity of the human the body allows low-loss transmission, termed as human body communication (HBC) and improves energy-efficiency. Conventional HBC implementations still suffer from significant radiation compromising physical security and efficiency. Our recent work has developed Electro-Quasistatic Human Body Communication (EQS-HBC), a method for localizing signals within the body using low-frequency transmission, thereby making it extremely difficult for a nearby eavesdropper to intercept critical personal data, thus producing a covert communication channel, i.e., the human body as a ‘wire’ along with reducing interference.

In this talk, I will explore the fundamentals of radio communication around the human body to lead to the evolution of EQS-HBC and show recent advancements in the field which has a strong promise to become the future of Body Area Network (BAN). I will show the theoretical development of the first Bio-Physical Model of EQS-HBC and how it was leveraged to develop the world’s lowest-energy (<10pJ/b) and world’s first sub-uW Physically and Mathematically Secure (AES 256) IoB Communication SoC, with >100x improvement in energy-efficiency over Bluetooth. I’ll also highlight how recent developments in mixed-signal circuit techniques allow orders of magnitude improvement in side-channel attack resistance of the encryption engines in such SoCs. Finally, I will highlight the possibilities and applications in the fields of HCI, Medical Device Communication, and Neuroscience including a video demonstration. I will highlight how such low-power secure communication in combination with in-sensor intelligence is paving the way forward for Secure and Efficient IoB Sensor Nodes.
