Scratch, Click & Vote: E2E voting over the Internet

Miroslaw Kutylowski and Filip Zagorski

Abstract: We present Scratch, Click & Vote voting scheme, which is a modification of the Punchscan and ThreeBallot systems. The scheme is end-to-end veryfiable and allows for voting over the Internet.

Security against malicious hardware and software used by a voter %TT is due to the fact that a voter's computer does not get any knowledge about the voter's choice. Moreover, it can change successfully a voter's ballot only with a small probability.

As a side result, we present a modification of the ThreeBallot that eliminates Strauss'-like attacks on this scheme.
