  • Classified material in the public domain: what's a university to do?

    Yesterday I posted some thoughts about Purdue University’s decision to destroy a video recording of my keynote address at its Dawn or Doom colloquium. The organizers had gone dark, and a promised public link was not forthcoming. After a couple of weeks of hoping to resolve the matter quietly, I did some digging and decided…

  • Building a better CA infrastructure

    As several Tor project authors, Ben Adida and many others have written, our certificate authority infrastructure has the flaw that any one CA, anywhere on the planet, can issue a certificate for any web site, anywhere else on the planet. This was tolerable when the only game in town was VeriSign, but now that’s just…

  • Breathalyzer Source Code Secrecy Endangers Minnesota Drunk Driving Convictions

    The Minnesota Supreme Court ruled recently that defendants accused of drunk driving in the state are entitled to have their experts inspect the source code for the software in the Intoxilyzer breath-testing machines used by police to gauge the defendants’ blood alcohol levels. The defendants argued, successfully, that they were entitled to examine and challenge…

  • On the future of voting technologies: simplicity vs. sophistication

    Yesterday, I testified before a hearing of Colorado’s Election Reform Commission. I made a small plug, at the end of my testimony, for a future generation of electronic voting machines that would use crypto machinery for end-to-end / software independent verification. Normally, the politicos tend to ignore this and focus on the immediately actionable stuff…

  • Counting Electronic Votes in Secret

    Things are not looking good for open government when it comes to observing poll workers on Election Night. Our state election laws, written for the old lever machines, now apply to Sequoia electronic voting machines. Andrew Appel and I have been asking a straightforward question: Can ordinary members of the public watch the procedures used…

  • Judge Suppresses Report on Voting Machine Security

    A judge of the New Jersey Superior Court has prohibited the scheduled release of a report on the security and accuracy of the Sequoia AVC Advantage voting machine. Last June, Judge Linda Feinberg ordered Sequoia Voting Systems to turn over its source code to me (serving as an expert witness, assisted by a team of…

  • Transit Card Maker Sues Dutch University to Block Paper

    NXP, which makes the Mifare transit cards used in several countries, has sued Radboud University Nijmegen (in the Netherlands), to block publication of a research paper, “A Practical Attack on the MIFARE Classic,” that is scheduled for publication at the ESORICS security conference in October. The new paper reportedly shows fatal security flaws in NXP’s…

  • NJ Voting Machine Tape Shows Phantom Obama Vote

    I’ve written before (1, 2, 3) about discrepancies in the election results from New Jersey’s February 5 presidential primary. Yesterday we received yet another set of voting machine result tapes. They show a new kind of discrepancy which we haven’t seen before – and which contradicts the story told by Sequoia (the vendor) and the…

  • Sequoia's Explanation, and Why It's Not the Whole Story

    I wrote yesterday about discrepancies in the results reported by Sequoia AVC Advantage voting machines in New Jersey. Sequoia issued a memo giving their explanation for what might have happened. Here’s the relevant part: During a primary election, the “option switches” on the operator panel must be used to activate the voting machine. The operator…

  • Evidence of New Jersey Election Discrepancies

    Press reports on the recent New Jersey voting discrepancies have been a bit vague about the exact nature of the evidence that showed up on election day. What has the county clerks, and many citizens, so concerned? Today I want to show you some of the evidence. The evidence is a “summary tape” printed by…
