Thats alarming news considering how much faith Estonia has shown in its e-voting system; And Estonia is a good example of why theyre reluctant to make the jump. \The Estonian system uses a security architecture that may have been adequate when the system was introduced a decade ago, but it is now dangerously out of date,\ said the report authored by J. Alex Halderman, assistant professor of computer science and engineering at University of Michigan, along with several security experts and Ph.D. students.
