Title: On cryptographic protocols for Norwegian internet voting
Abstract:
Estonia is already implementing Internet voting in the national scale. In Norway, the plan is to have pilot elections in 2011 and full-scale elections in 2017. Differently from Estonia, Norwegian elections are supposed to be verifiable. Moreover, they should remain verifiable even in the presence of untrusted voter PCs. In 2009, we proposed a setting ("code-verification") for Norwegian Internet voting, that was also adopted in Norway. In this talk, I will explain the setting and two different code-verification voting protocols. The first protocol was originally proposed in 2009. Norway is going to use another protocol, which is more efficient but less secure. The second protocol we explain is as efficient as the official Norwegian protocol but achieves better security.
