Side-Channel Attack-Resistant HMAC-SHA256 Accelerator With Boolean and Arithmetic Masking in Intel 4 CMOS

Side-Channel Attack-Resistant HMAC-SHA256 Accelerator With Boolean and Arithmetic Masking in Intel 4 CMOS 150 150
Author(s): Sachin Taneja, Vikram B. Suresh, Raghavan Kumar, Vivek De, Sanu K. Mathew

Abstract:

This work describes a side-channel attack (SCA)-resistant hash-based message authentication code (HMAC) accelerator with secure hash algorithm 2 (SHA-2) using Boolean and arithmetic masking along with the first-reported ASIC implementation in Intel 4 CMOS with 10 M measured traces. Previously reported masked datapath suffers from high area/performance overheads (>100%) designs due to …

Abstract:

This article presents a two-step incremental analog-to-digital converter (ADC) that achieves high resolution and energy efficiency while substantially easing the input driving constraints and interstage gain variation. By employing a level-shifted sub-ranging architecture with an input-tracking (IT) feature, the design obviates direct input sampling, thereby significantly relaxing the demands on …
