Title: "Electronic voting systems"

by

Mr. ZHANG, Guangda

As the widespread of the touch screen, DRE, devices in US presidential 
elections, electronic voting gradually becomes more popular. However, it 
has been a long time for the voters to get a simple acknowledgement of 
their votes, without any possibility to check whether their votes have 
been correctly counted.

David Chaum introduced the voter-verifiable election and provided a 
practical voting scheme "a practical voter-verifiable election scheme", 
which provides the voters a receipt. The receipt can be used to check 
whether the ballot is counted correctly but cannot be used to tell others 
how the voter voted. The scheme place trust in several components of the 
voting system, which raises the reliability and security of the whole 
voting system.

In this paper, we will introduce this electronic voting scheme in a 
clearer and more acceptable way. Also we will conduct threat analysis on 
this scheme from different aspects, including the voting process, the 
tallying process, and some technical details. The strength and drawbacks 
of the cryptographic issue are also analyzed. Some suggestions for the 
scheme are provided at the end.
