ChaCha20-Poly1305

Hardware implementation of the ChaCha20-Poly1305 AEAD construction

Introduction

This is a hardware implementation of the Authenticated Encryption construction ChaCha20-Poly1305. The functionality matches the description in RFC 7539 and is needed for example for the TLS and DTLS cipher suites in RFC 7905.

Status

Not done.

The ChaCha core and integration is done. The Poly1305 implementation is started, but is nowhere near completion. Right now it is modelling in Python and architecture design.

Implementation

The core is written in Verilog 2001 and is based around the ChaCha core.

The Poly1305 part of the core will (probably) have a processing cycle time matching the ChaCha core.
