Colloquium Topic: Security Issues in Electronic Voting

Many voting precincts are moving to electronic voting machines before the security issues are fully understood. We had a chance to examine the source code in one widely used machine and found it highly lacking in security and easily subject to tampering. There are ways to mitigate the insecurity in voting machines. One way is to provide a voter verifiable paper trail, and to have surprise recounts comparing the paper tally to the electronic one. We will discuss other mitigation strategies as well and explain why it is so difficult to design a fully electronic voting system that is secure. I was also on the government formed external security review committee for SERVE, designed for military and overseas civilians to vote over the Internet. We published an analysis of the security problems with the system and I will discuss these in the talk.
