16:00-17:00 | Ron Rivest (MIT): The Security of Voting Systems Abstract: While running an election sounds simple, it is in fact extremely
challenging. Not only are there millions of voters to be
authenticated and millions of votes to be carefully collected,
counted, and stored, there are now millions of “voting machines”
containing millions of lines of code to be evaluated for security
vulnerabilities. Moreover, voting systems have a unique requirement: the
voter must
not be given a “receipt” that would allow them to prove how they voted to
someone
else - otherwise the voter could be coerced or bribed into voting a
certain way.
This lack of receipts makes the design of secure voting system much more
challenging
than, say, the security of banking systems (where receipts are the norm).
We discuss some of the recent trends and innovations in voting systems, as well as some of the new requirements being placed upon voting systems in the U.S., and describe some promising directions for resolving the conflicts inherent in voting system requirements, including some approaches based on cryptography. We also describe the use of the “Scantegrity II” end-to-end voting system, developed by David Chaum and researchers from MIT, GWU, UMBC, Ottawa, and Waterloo, in last November's election in the city of Takoma Park, Maryland. |
