Evaluating the Security of Electronic Voting Systems

Electronic voting systems have been introduced to improve the voting process. Since their inception, they have been controversial, because both the technologists and the general public realized that they were losing direct control over an important part of the voting process: counting the votes.

A quote attributed to Stalin says: "Those who cast the votes decide nothing. Those who count the votes decide everything." It is clear that voting systems represent a critical component of a democracy. Although the consequences of a malfunctioning electronic voting system are not as readily apparent as those for air traffic control or nuclear power plant control systems, they are just as important, because the well-being of a society depends on them.

While most critical systems are continuously scrutinized and evaluated for safety and correctness, electronic voting systems are not subject to the same level of scrutiny. A number of recent studies have shown that most (if not all) of the electronic voting systems being used today are fatally flawed, and that their quality does not match the importance of the task that they are supposed to carry out.

In the Summer of 2007, the Security Group of UCSB participated in the Top-To-Bottom Review (TTBR) of the electronic voting systems used in California. This was a first-of-its-kind review, where the evaluators had unprecedented access to the systems' source code, hardware, and associated documentation.
