Mental Poker

CS227 Mental Poker Project: An implementation of the Fast Mental Poker protocol by Wei and Wang.

Installation

python3 -m pip install -r requirements.txt

We have tested using Python 3.8

Run

python3 poker.py

The above program does the following:

1. performs the multi-party deck generation between two parties, Alice and Bob
2. performs the multi-party shuffle on the generated deck
3. Alice and Bob each draw 7 cards from the deck
4. Alice and Bob reveal their cards and the person with the best 5-card hand wins

Implementation Details

• set up P2P authenticated message exchange between players via the p2pnetwork python library
