ECE6612 Project

This repository contains tools and experiments for exploring QUIC and DNS over QUIC (DoQ) protocols. It leverages the aioquic library, a Python implementation of QUIC and HTTP/3.

Getting Started

Prerequisites

• Python 3.8 or higher
• git for managing submodules

Setup

1. Clone the repository:

   git clone --recursive https://github.com/MathMasterMind/DoQinRetrospect.git

2. Run the setup script:

   ./runner.sh

   This script:

   • Initializes and updates the aioquic submodule.
   • Sets up a Python virtual environment.
   • Installs required dependencies.
   • Applies the nopad.patch for the unpadded QUIC experiment.
   • Runs the unpadded_connection.py script.

Experiments

Unpadded QUIC Experiment

The UnpaddedExperiment directory contains:

• nopad.patch: A patch to modify the aioquic library for unpadded QUIC connections.
• unpadded_connection.py: A script to test unpadded QUIC connections.

To run this experiment, execute:

./runner.sh

Retry Experiments

The RetryExperiment directory includes:

• DoT_Client_Hello.py: Simulates a DNS-over-TLS client hello.
• DoT_No_Reply.py: Sends a DoT client SYN Packet.
• DoQ_Initial.py: Sends a DoQ client Initial Packet.

Use Wireshark to monitor traffic

Server Acquisition

The ServerAquisition directory contains tools for analyzing QUIC servers:

• ip_to_globe.py: Maps IP addresses to geographical locations.
• quic_resolvers_src1.py and quic_resolvers_src2.py: Scripts for resolving QUIC servers.
