casbtosint/py-ipv8: Python implementation of Tribler's IPv8 p2p-networking layer https://github.com/casbtosint/py-ipv8

 FAQ:

• Q: Is this the new official Layer 3 solution for the Internet?
• A: No, the naming is a 10-years-old mockery of the deployment failure of IPv6 (which we sincerely hope will be deployed properly at some point in time).

What is IPv8 ?

IPv8 aims to provide authenticated communication with privacy. The design principle is to enable communication between public key pairs: IP addresses and physical network attachment points are abstracted away. This Python 3 package is an amalgamation of peer-to-peer communication functionality from Dispersy and Tribler, developed over the last 18 years by students and employees of the Delft University of Technology. The IPv8 library allows you to easily create network overlays on which to build your own applications.

IPv8 Objectives

• Authentication. We offer mutual authentication using strong cryptography. During an IPv8 communication session, both parties can be sure of the other party’s identity. IPv8 users are identified by their public key. The initial key exchange is designed so that secrets are never transmitted across the Internet, not even in encrypted form. We use a standard challenge/response protocol with protection against spoofing, man-in-the-middle, and replay attacks.
• Privacy. IPv8 is specifically designed for strong privacy protection and end-to-end encryption with perfect forward secrecy. We enhanced the industry standard onion routing protocol, Tor, for usage in a trustless environment (e.g. no trusted central directory servers).
• No infrastructure dependency. Everybody is equal in the world of IPv8. No central web server, discovery server, or support foundation is needed.
• Universal connectivity. IPv8 can establish direct communication in difficult network situations. This includes connecting people behind a NAT or firewall. IPv8 includes a single simple and effective NAT traversal technique: UDP hole-punching. This is essential when offering privacy without infrastructure and consumer-grade donated resources.
• Trust. You can enhance your security if you tell IPv8 which people you know and trust. It tries to build a web-of-trust automatically.

Dispersy

This repository is no longer maintained, in favor of the IPv8 networking library.

The Distributed Permission System, or Dispersy, is a platform to simplify the design of distributed communities. At the heart of Dispersy lies a simple identity and message handling system where each community and each user is uniquely and securely identified using elliptic curve cryptography.

Integrated NAT Puncturing

Nowadays almost all devices have a network connection, with a lot of them running in challenged network environments. Challenging conditions can be found in a wide range of networks, i.e. Peer-to-Peer networks (P2P), and delay tolerant networks (DTNs). These networks have several limitations, like having long communication delays, very low data rates, and unstable links.

P2P networks are particularly challenging due to nodes not always being online, NAT-firewall constrained Internet connections, and frequent interaction with potentially malicious nodes. Smartphones pose another challenge due to their limited processing capability and battery lifetime.

Dispersy was designed to be capable of running in challenged network environments. It does this by minimizing the needed resources by using optimized algorithms and protocols.

Decentralized

Dispersy is fully decentralized. It does not require any server infrastructure and can run on systems consisting of a large number of nodes. Each node runs the same algorithm and performs the same tasks. All nodes are equally important, resulting in increased robustness. Dispersy offers distributed system developers both one-to-many and many-to-many data dissemination capabilities. Data is forwarded between nodes. All injected data will eventually reach all nodes, overcoming challenging network conditions.

Dispersy uses elliptic curve cryptography to identify the different nodes in a secure and anonymous way.

Goal

Dispersy is designed as a building block for implementing fully decentralized versions of, for instance Facebook, Wikipedia, Twitter, or Youtube. These Web 2.0 applications often require on a direct Internet connection to their central servers, but can now be implemented in a distributed way

Key Features

Key features of Dispersy are:

• stateless synchronization using Bloomfilters
• decentralized NAT traversal
• performance that can scale to over 100,000 bundles

Dispersy is intergated in the BitTorrent client Tribler and show that it is performing very well in various real-time challenged network scenario’s (3G and WIFI).
