Project Overview

This repository contains the codebase for a project involving the implementation of the Ishai-Sahai-Wagner (ISW) protection scheme to safeguard the Secure Hash Algorithm 3 (SHA-3) against Differential Power Analysis (DPA) attacks on ARM Cortex M4 microcontrollers. The implementation also includes a shuffling technique to enhance the robustness of the ISW scheme.

This project was supervised by Alessandro Barenghi.

Repo Structure

This repository is organized as follows:

• x86_tests/: Contains the source code for the x86 implementation of the algorithm. This allows for performing tests without the need for cross-compiling.

• STMF4DISCOVERY/: Contains the source code for the implementation designed specifically for the STMF4 Discovery microcontroller.

Building and Testing the Project

x86 Implementation

1. Navigate to the x86_tests/ directory.
2. Compile and build the project according to your environment and the build instructions in the project files.
3. Run tests as needed.

STM32F4 Discovery Microcontroller Implementation

For this, i recommend using PlatformIO with the following platformio.ini settings:

[env:disco_f407vg]
platform = ststm32
board = disco_f407vg
framework = libopencm3
upload_protocol = mbed

1. Navigate to the STMF4DISCOVERY/ directory.
2. Compile and build the project using PlatformIO.
3. Flash the compiled binary to your STM32F4 Discovery board using the PlatformIO upload feature.
4. Run tests on the hardware as needed.
