BoRoVo (Boardroom Voting)

Motivation

One of the possible practical applications of electronic voting protocols are the elections of smaller scale, such as among board of directors, in university committees, or in classrooms. Such elections are often conducted among small groups of voters, in ad hoc way, and with limited central infrastructure, thus posing a different set of challenges, than large-scale political elections. Currently, they are most often conducted via raising of hands or paper voting, which, however, excludes the voters, that are not physically present in the same room as others, from participating in the voting. Therefore, an application that enables secure remote electronic voting, would be practical in cases of some of the voters being able to participate also while travelling or not being able to attend the meeting in person for some other reason. A typical application setting for such voting is shown in Figure 1.

Results

For enabling decentralised boardroom voting, BoRoVo, an application for Android smartphones has been developed, implementing a protocol that enables private, verifiable and robust decentralized boardroom voting and elections. The usability of the application was evaluated in user studies, resulting in usability score well above average (84,58 out of 100).

The BoRoVo application with the user manual is available on request. 

The development of the application and the application have been presented at several scientific venues, e.g. at the 6th International Conference on Electronic Voting (EVOTE) 2014 (see Figure 2).
