Dr. Avi Rubin of the Johns Hopkins’ Information Security Institute gave the keynote today, Electronic Voting: A case study of how closed systems fail, at the Secure Trusted Operating System Consortium Symposium underway at George Washington University. Dr. Rubin’s research identified critical security flaws in e-voting machine manufacturer Diebold Inc.’s software. The company announced this past July that it was awarded a $55.6m contract by the state of Maryland for its touch screen voting technology and related support services.
