ChipWhisperer: Past & Future of a FPGA-based Research Tool
summary
An open-source, FPGA-based single-channel oscilloscope measures tiny power differences to perform side-channel attacks and ships with schematics, FPGA bitstreams, firmware and host code. It implements a feature called trace whisper that uses ARM trace pins to trigger captures and aims to move parsing from OpenOCD into the FPGA. The board uses an Artix-7 A35 where side logic consumes most fabric, and it supports power-triggered capture to align repeated public-key operations, though fitting full parsing into the FPGA is challenging.
