Mixnet v2 Simulation

How to run

Make sure that all dependencies specified in the requirements.txt in the project root, and run the following command to run the simulation:

python main.py

The following parameters can be configured:

usage: main.py [-h] [--running-time RUNNING_TIME] [--num-nodes NUM_NODES] [--num-mix-layers NUM_MIX_LAYERS]

Run simulation

options:
  -h, --help            show this help message and exit
  --running-time RUNNING_TIME
                        Running time of the simulation (default: 30)
  --num-nodes NUM_NODES
                        Number of nodes in the network (default: 2)
  --num-mix-layers NUM_MIX_LAYERS
                        Number of mix layers in the network (default: 2)

Development Status

• Modified Sphinx
  • Without encryption
  • With encryption
• P2P Broadcasting
  • Naive 1:N
  • More realistic broadcasting (e.g. gossipsub)
• Forwarding messages through mixes, and then broadcasting messages to all nodes
• Cover traffic
  • With a constant rate
  • More sophisticated rate (e.g. based on the approximate block interval)
• Mix delays
  • Naive random delays
  • More sophisticated delays (e.g. Poisson)
• Adversary simulations
  • Observing message emission patterns
  • Correlating senders-receivers based on timing
  • Active attacks
  • Reporting & Visualization
