Today, the Federal District Court for the Northern District of Georgia unsealed a 96-page report that I wrote w/ Prof. @_aaspring_ from @AuburnU. It describes serious vulnerabilities we found in Georgia's Dominion ImageCast X ballot marking devices.

I don't know whether the President actually has the authority to order these changes, but if not, Congress should see them as a starting point for long-needed election security reforms. Here's the full order:.

Only some states require maintaining current federal voting equipment certification, and many will only consider the new standards when they go to purchase new equipment. Still, this order could be an important step forward and accelerate the adoption of more secure systems.

The order also prohibits ballot-marking devices that record votes using barcodes, except as necessary for accessibility.

EAC must re-certify all equipment under the VVSG 2.0 standard, which is much stronger than VVSG 1.0 under which most current equipment was certified. Among other big security improvements, it requires paper ballots!. The era of paperless DRE voting is over.

A new executive order just dropped that, if implemented, promises to significantly strengthen federal certification of voting machines.

From a security perspective, elections are much safer when there's a decisive outcome than when they hinge on razor-thin margins in a few states. But what about next time? How many voters will continue to call for necessary election security improvements?.

Today's the 1st day of class at @UMich and we're in hour 24 of a major IT outage. Despite the disruption, it's been great to see colleagues innovate and help each other work around the downtime. Big thanks to everyone at @umichTECH who's been up all night to bring us back online.
