5/19/04 1:30 PM - ITL SEMINAR SERIES: Secret-Ballot Receipts: True Voter-Verifiable Elections

A new kind of receipt sets a far higher standard of security by letting voters verify the election outcome -- even if all election computers and records were compromised. The system preserves ballot secrecy, while improving access, robustness, and adjudication, all at lower cost. The concept of such receipts will be introduced in a way that requires no special background. The properties and some special features achieved will also be described from first principles. A number of example ways to realize the concepts will be sketched and there may be a demonstration of a new one that promises to be applicable shortly for use at polling places in the United States. bio: Dr. David Chaum is a pioneer in electronic cash and is also known for proposing cryptographic techniques that allow individuals to protect their identity while securely interacting with others. Among these techniques is one for secure electronic election technology and others to provide credential mechanisms and untraceable communication. David has over 50 original publications in the area of cryptography and dozens of patents issued and pending. With a Ph.D. in Computer Science from Berkeley, he taught at several universities, established one of the leading crypto research groups, and founded DigiCash and the International Association for Cryptologic Research. He is affiliated with several companies, universities and international projects.
