A new analysis of actual, real-life, online voting systems is more bad news for online voting.
From the abstract of “Security Analysis of the Democracy Live Online Voting System“:
returned in the mail, the software sends the voter’s identity and ballot choices to Democracy Live, an unnecessary security risk that jeopardizes the secret ballot. We recommend changes to make the platform safer for ballot delivery and marking. However, we conclude that using OmniBallot for electronic ballot return represents a severe risk to election security and could allow attackers to alter election results without detection.
Even in the post-Coronavirus world, online voting just isn’t safe enough to use in real life elections.
