Security for E-Voting in Public Elections
Avi Rubin, AT&T Labs–:Research

In this talk I will discuss the security considerations for remote electronic voting in public elections. In particular, I'll examine the feasibility of running national federal elections over the Internet. The focus of this talk is on the limitations of the current deployed infrastructure in terms of the security of the hosts and the Internet itself. I will conclude that at present, our infrastructure is inadequate for remote Internet voting.

Online Privacy: Promise or Peril?
Lorrie Faith Cranor, AT&T Labs--Research

This talk will discuss the privacy concerns raised by online data-collection practices, as well as the efforts to address these concerns through laws, self-regulation, and technology. The talk will focus on the emerging Platform for Privacy Preferences (P3P) standard. P3P-enabled Web sites make statements about how they handle user data available in a machine-readable (XML) format. P3P-enabled browsers can "read" these statements automatically and compare them to the user's privacy preferences.

Getting to Grips with Secure DNS
Jim Reid, Nominum, Inc.

Secure DNS (DNSSEC) has been developed as a way of validating the data in the DNS and preventing spoofing attacks. The protocol uses public-key cryptography to digitally sign DNS traffic. This talk explains the new resource records that have been added to the DNS and how to use the tools in BIND9 that are provided for creating and maintaining signed zones. The practical and operational problems of deploying DNSSEC, notably key management, will also be discussed.

Work-in-Progress Reports
Session Chair: Greg Ganger, Carnegie Mellon University

Short, pithy, and fun, Work-in-Progress reports introduce interesting new or ongoing work. If you have work you would like to share or a cool idea that's not quite ready for publication, send a one- or two-paragraph summary to We are particularly interested in presenting students' work. A schedule of presentations will be posted at the conference, and the speakers will be notified in advance.

Active Content: Really Neat Technology or Impending Disaster?
Charlie Kaufman, Iris Associates

From Java-enabled Web pages to self-extracting zip files, the world has become addicted to active content. This powerful technique improves data compression, CPU and network efficiency, and interactive user interfaces. The price? It's nearly impossible to make secure. This talk discusses surprising places we use active content, the security threats we are ignoring, and what we as individuals and as a community can do about it.
