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 an static random-access memory (SRAM)-based digital compute-in-memory (CIM) compiler implemented with 3 nm high- $\kappa $ metal gate (HKMG) FinFET technology, supporting flexible INT8 and FP16 formats for weight and activation multiply-accumulate (MAC) operations, offering configuration flexibility, high accuracy, and improved area and power efficiency. The FP16 digital …
