This project implements the stateless hash-based signature scheme SPHINCS-256 for an Arduino Due board. The scheme provides an effective replacement for digital signature in a post-quantum world. It combines the extended Merkle's signature scheme (XMSS), improved Winternitz one-time signatures (WOTS+), and "Hash to Obtain Random Subset" Trees (HORST) few-time signatures scheme.
The goal of this project is to to reproduce the implementation of SPHINCS-256 on an STM32L100XC ARM Cortex-M3 but for a SAM3X8E ARM Cortex-M3 CPU using the Atmel Studio framework (ASF) such that environmental attacks, like side-channel analysis or fault injection, can be performed.

The project was intended to work with the following software :
- An Atmel SAM3X8E ARM Cortex-M3 board (Arduino Due)
- Arduino IDE 1.8.1
- Atmel Studio 7.0
- Program Arduino Due with Atmel Studio 7
