A few years back I implemented the scheme described in "A practical secret
voting scheme for large scale elections", by Atsushi Fujioka, Tatsuaki
Okamoto, and Kazuo Ohta (Proceedings AUSCRYPT '92, 1993, 244-251). The system
is called E-Vox and can be found at http://theory.lcs.mit.edu/~cis/voting/votin
g.html
This summer (probably July or August) I'm planning on turning it into an Open
Source project, since neither Ben Adida nor I are currently doing work at MIT.
The web page given above also has a list of other Electronic Voting projects.
