In my previous blog posts about Solon I have mostly focused on the high-level interaction between Solon and Liquid Feedback. Now it is time to dive into the good stuff: the cryptographic e-voting algorithms that scientists have been developing since the 80's. But first, we need to understand our requirements. What does it mean to develop a secure e-voting algorithm?
Most academic articles on e-voting algorithms will begin with a recital of requirements for a secure election or secure voting. The list is quite long, so sometimes an article may omit some of these, but there is a well established consensus that what I will write about in this post is what a secure election is about. I have taken this list from a really well written overview of different e-voting algorithms: "A framework and taxonomy for comparison of electronic voting schemes" by K Sampigethaya, R Poovendran, Computers & Security, Elsevier 2006. I recommend you read it if you want a deeper understanding on this topic.
