Computer Voting is Open to Easy Fraud, Experts Say

The software that runs many high-tech voting machines contains serious flaws that would allow voters to cast extra votes and permit poll workers to alter ballots without being detected, computer security researchers said yesterday.

"We found some stunning, stunning flaws," said Aviel D. Rubin, technical director of the Information Security Institute at Johns Hopkins University, who led a team that examined the software from Diebold Election Systems, which has about 33,000 voting machines operating in the United States.

The systems, in which voters are given computer-chip-bearing smart cards to operate the machines, could be tricked by anyone with $100 worth of computer equipment, said Adam Stubblefield, a co-author of the paper.

"With what we found, practically anyone in the country — from a teenager on up — could produce these smart cards that could allow someone to vote as many times as they like," Mr. Stubblefield said.
