Title:  How to make and break a Cortex-M3-based cryptographic token

Abstract
PITCHFORK is a new device for compartmentalizing key material and to do mostly post-quantum cryptographic operations in a small and durable USB device. In this workshop the hardware and software design will presented, together a comprehensive threat model, attack surface and mitigations.
The goal of this workshop is to inspire the audience to:
  • build their own PITCHFORKS and play with crypto on them
  • to make the audience have fun breaking everything built in 1/ or similar devices.
