ed25519

This is a hardware implementation of the ed25519 public key signature system. The core is implemented in Verilog (2001).

Introduction

The ed25519 public key signature system is used in Tor. As part of the Cryptech project we want to support the ed25519 signing in the HSM.

The references used for this implementation are:

• The DJB implementation and paper.
• The NaCl on 8-bit AVR MCU project and paper.
• Daniel Cegielka Suggested using the OpenBSD signify tool as reference:
