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
