I was able to vote twice, is it normal?

Yes! In Belenios, you may vote as many times as you wish, until the election closes. Only the last vote is kept (and you may check its presence in the public ballot box using your tracking number).

Is it safe to use a Google account to administer an election?

If you use a Google account to administer an election, Google won't get any information about the votes of the participants (nor will you!). However, in principle, Google could impersonate you, and get the list of the email addresses of the participants. In many cases, the risk of doing so would be higher on the Google side (breaching its privacy policy) than on your side. Also, once you're logged using a Google account, it may be difficult to be effectively logged out from Google. For this, you may prefer to use the private navigation mode.

I've seen that I must accept cookies to vote, why?

We use cookies to store your language preference (if you chose a different language than the default one) and for session management. The purpose of the latter is to link the different requests of the voter during the voting phase. Once you have voted, all identifying information is discarded. In particular, we do not track voters or use cookies for statistical or marketing purposes.

What is the difference between Belenios and Helios?

While the implementations of Belenios and Helios are distinct, the voting protocol underlying Belenios (cf corresponding research report) builds on Helios. The main difference is the use of credentials, that prevent ballot stuffing. In Belenios, each voter receives a private credential (by email) while the election server receives only the corresponding public credential. Even if the election server is compromised, no ballot can be added!

By default, the Belenios server stores the decryption key, similarly to Helios. However, the Belenios platform also provides an easy way for the election administrator to add decryption authorities. The decryption keys are then generated locally on the computer of each decryption authority and only the public keys are transmitted to the server.

Why Belenios is named Belenios?

Belenios is a variant of Helios. Helios is the personification of the Sun in Greek mythology while Belenos is the Sun god from Celtic mythology. We made it Belenios to sound like Helios.
