Peer-to-Peer Secure Update

This project aims to provide a framework to securely distribute system update using peer-to-peer procotol that works in heterogeneous network environment, in the presence of NATs and firewalls, where there is no necessarily direct access from a management node to the devices being updated.

The framework combines several key techniques:

1. STUN-based UDP hole punching to discover and open NAT bindings
2. A gossip protocol to deliver short messages to distribute update notifications
3. BitTorrent to securely distribute the software update

This project is part of Federated RaspberryPi micro-Infrastructure Testbed - FRuIT.
