Tuesday's proposal, which passed unanimously, took a slightly less restrictive approach. It called for future DREs to include audit mechanisms, and it said TGDC should "ensure that systems that produce independently verifiable voting records are reliable and provide adequate support for audits."
But the proposal that passed stopped short of requiring the current generation of e-voting machines to add on audit mechanisms. "Election officials and vendors have appropriately responded to the growing complexity of voting systems by adding more stringent access controls, encryption, testing, and physical security to election procedures and systems," the proposal said.
The new proposal addressed some TGDC concerns about accessibility for disabled people and what to do with existing e-voting machines, Rivest said by phone. "It's not a motion to encourage people to dump their machines in any way," he said.
The Election Assistance Commission will hear a report about the TGDC action at a meeting Thursday, but the new audit standards likely wouldn't go into effect until after 2010.
