Master’s degree student Zach Kahleifeh and assistant professor Himanshu Thapliyal, both in the University of Kentucky Department of Electrical and Computer Engineering, received an Outstanding Student Paper Award via the IEEE 6th World Forum on Internet of Things.
The paper, titled “2-Phase Energy-Efficient Secure Positive Feedback Adiabatic Logic for CPA-Resistant IoT Devices,” reflects research supported by the NSF CAREER Award Thapliyal received in 2019.
Due to COVID-19, the World Forum on Internet of Things, originally scheduled to take place in New Orleans, Louisiana this June, will be held online.
The abstract of the paper is below.
“Internet of Things (IoT) devices are mostly areas constrained and operate on a limited battery supply and therefore have tight energy budgets. CMOS implemented Lightweight cryptography (LWC) such as Present-80 are vulnerable to side-channel attacks such as Correlation Power Analysis (CPA). Adiabatic Logic is an emerging circuit design technique that can reduce energy consumption and be CPA resistant. Many existing adiabatic logic families use a 4-phase clocking scheme which pays a large area penalty. Thus, in this paper, we propose 2-EE-SPFAL, a 2-phase clocking scheme implementation of an existing adiabatic family known as EE-SPFAL. We explore 2-phase sinusoidal waves in terms of energy efficiency and security. To demonstrate energy savings and security against CPA attacks we construct one round of PRESENT-80 in both CMOS and 2-EE-SPFAL. Simulations were conducted using 45nm technology in Cadence Spectre. At 12.5MHz, our results show an average energy saving of 50% between CMOS and 2-EE-SPFAL. Furthermore, we performed a CPA attack on both the CMOS and 2-EE-SPFAL to validate the CPA-resistance of the 2-EE-SPFAL.”
