Usable Verifiable Secrecy-Preserving E-Voting

Kulyk, Oksana; Ludwig, Jonas; Volkamer, Melanie; Koenig, Reto E.; Locher, Philipp

In this paper we propose the usage of QR-Codes to enable
usable veriable e-voting schemes based on code voting. The idea { from a
voter's perspective { is to combine code voting proposed by Chaum with
the cast-as-intended verication mechanism used e.g. in Switzerland (using
a personal initialization code, return codes per option, a conrmation code
and a nalisation code); while all codes to be entered into the e-voting
system by voters are available as QR-Code (i.e. one personalised QR
voting code per voting option and one personal conrmation QR-Code).
We conduct a user study to evaluate the usability and user experience
of such an approach: both the code sheets and the election webpage are
based on usability research in this area but adopted for our idea. As
our proposal performs good wrt. usability, we discuss how such usable
front-ends enable more secure e-voting systems in respect to end-to-end
veriability and vote secrecy.
