First, make sure that all dependencies specified in the requirements.txt in the project root. Then, configure parameters in the config.yaml, and run the following command:

python main.py --config ./config.yaml

The simulation runs during a specified duration, prints the results to the console, and show some plots.

Mixnet Functionalities

Modified Sphinx
- Without encryption
- With encryption
P2P Broadcasting
- Naive 1:N
- More realistic broadcasting (e.g. gossipsub)
Sending a real message to the mixnet at the promised interval
- Each node has its own probability of sending a real message at each interval.
Cover traffic
- All nodes have the same probability of sending a cover message at each interval.
Forwarding messages through mixes, and then broadcasting messages to all nodes if the message is real.
Mix delays
- Naive random delays
- More sophisticated delays (e.g. Poisson) if necessary

Adversary Models

Identifying nodes emitting messages around the promised interval.
- With partial visibility
Correlating senders-receivers based on timing
Active attacks
Reporting & Visualization
- With quantifying the effect of attacks above based on parameter changes.
