(I have been refered to Crypto.SE via a comment at Security.SE)
Assume a university want to elect the student council. This was done via paper ballot and there is a need to reach more students for voting, so electronic voting is on the table.
While researching existing solutions I came across Helios: helios voting and agora voting
Both seem to implement somewhat peer-reviewed schemes to do a online vote, but my impression is that the devil might hide in the details.
Has anyone here experience using these schemes? We plan to implement such an online voting scheme and would authenticate the voters via the university LDAP. Which cryptographic obstacles or security problems could we face?
