A controversial electronic voting system must undergo federal security testing before it can be approved for use in California, Secretary of State Bruce McPherson said Tuesday. Diebold Election System's optical scan and touch-screen voting systems...will have their state certification delayed for the second time, McPherson said. We have determined that there is sufficient cause for additional federal evaluation," he said in a statement. "Unresolved significant security concerns exist with respect to the memory card" because the federal government never reviewed the software that programs the card, said Caren Daniels-Meade, head of the secretary of state's election division, in a letter to Diebold. "We strongly believe it is the duty and responsibility of the secretary of state and you to make sure that the ultimate users of your products -- the voters of California -- have a voting system that has been thoroughly and rigorously evaluated." Diebold officials declined to comment directly on McPherson's concerns. The secretary of state first refused to certify the Diebold systems in July, after 20 percent of the new, printer-equipped electronic voting machines malfunctioned during a test in San Joaquin County.
