6.857 Final Project

Apollo

A secure, anonymized voting system using the Paillier cryptosystem

How to use virtualenv

Inside apollo/:

virtualenv env -p python3

To activate:

source env/bin/activate
pip install -e .

If you get an error message that includes the following lines:

  Running setup.py install for Flask-XML-RPC
    Skipping installation of /afs/athena.mit.edu/user/r/s/rsridhar/Desktop/6.857/Apollo/apollo/env/lib/python3.4/site-packages/flaskext/__init__.py (namespace package)
      File "/afs/athena.mit.edu/user/r/s/rsridhar/Desktop/6.857/Apollo/apollo/env/lib/python3.4/site-packages/flaskext/xmlrpc.py", line 252
        except Fault, fault:
                    ^
    SyntaxError: invalid syntax

you need to use 2to3 to fix xmlrpc.py to work with python3:

2to3 -w env/lib/python3.x/site-packages/flaskext/xmlrpc.py

Note you will need to fill x with your appropriate version number.

To deactivate:

deactivate

Building

Execute the following script to run the system with n talliers.

./run.sh n

There are now 4 ways to interact with the running system. The preferred is to use localhost:7000 to create an election, and use localhost:7777 to cast your votes.

Alternatively, less-offline-runthrough.py will create an election with preset candidates and voter ids. You must go to localhost:7777 to cast your vote and end the election.

Running demo.py will start an election using pre-set candidates corresponding to the 2016 US Presidential Race, with a pre-set list of valid voter ids.

Finally, offline-runthrough.py will create an election and execute votes, requiring no website interaction.

Debugging
