PAx5

Note

This repository is archived because I am building a version with better integration in the pax-devices repository.

Description

PAx5 is a home automation platform designed to be secure, stable and powerful.

# Hardware is centered around an ultra-low-power ARM Cortex-M0+ and a sub-GHz radio.

# For security:

  • AEAD (Authenticated Encryption with Associated Data) using the 128 or 256 bits key ChaCha20 algorithm (the new protocol used in HTTPS, TLS, OpenSSL, ...);
  • Unique, random, session keys;
  • Communication protocol designed to withstand the known attacks against these type of communications.

# Stability is increased with:

  • the radio module's power is generally enough to not require intermediary routers;
  • designed for high availability, redundant, gateways.
