Foreign forces spend a lot of time and effort on influencing and confusing ones who elect. But what if they can simply change your voice electronically? Or even easier: determine the election result? At the election in 2017, many municipalities would not count ballots by hand. The voters in Finnmark in 2018 voted on the Internet, as do voters in Switzerland and Estonia. American voters use electronic voting machines. We look at how such systems can be attacked and how cryptography can protect us.
Kristian Gjøsteen is a professor of mathematical cryptology at NTNU. He developed the cryptological solution that was used for internet voting at the municipal elections in 2011 and the Storting election in 2013. He has analyzed and demonstrated attacks against electronic identities, such as BankID.
