Watson Research Center Opportunistic Use of Content Addressable Storage for Distributed File Systems Niraj Tolia, Carnegie Mellon University and Intel Research Pittsburgh; Michael Kozuch, Intel Research Pittsburgh; Mahadev Satyanarayanan, Carnegie Mellon University and Intel Research Pittsburgh; Brad Karp, Intel Research Pittsburgh; Thomas Bressoud, Denison University and Intel Research Pittsburgh; Adrian Perrig, Carnegie Mellon University	INVITED TALKS How to Build an Insecure System out of Perfectly Good Cryptography Radia Perlman, Sun Microsystems Laboratories Problems in network security systems tend not to be subtle mathematical flaws in the cryptography, but instead broader system issues. This talk discusses deployed systems or standards with such flaws. It includes a public-keyxbased system with no advantages over a secret-keyxbased system, one in which encryption was used where what was really needed was integrity protection, one in which adding security decreased the reliability and did nothing to enhance the security of the system, unmanageable or unscalable PKI models, and an email standard that allowed forging signatures.

Flexibility in ROM: A Stackable Open Source BIOS Adam Agnew and Adam Sulmicki, University of Maryland at College Park; Ronald Minnich, Los Alamos National Labs; William Arbaugh, University of Maryland at College Park Console over Ethernet Mike Kistler, Eric van Hensbergen, and Freeman Rawson, IBM Austin Research Laboratory Implementing Clonable Network Stacks in the FreeBSD Kernel Marko Zec, University of Zagreb	GURU SESSIONS Release Engineering in a Large Distributed Project Scott Long, FreeBSD Project Scott's experience with FreeBSD dates back to the fall of 1992, when he discovered 386BSD-0.1. Since obtaining his src commit privileges in 2000, he has contributed to and maintained RAIDframe, the UDF filesystem, and several hardware drivers. In November 2002 he joined the FreeBSD Release Engineering team and quickly assumed the lead for the 5.0 release. He is currently working with the FreeBSD community to define the path for the 5.x series. His day job is as a software engineer for Adaptec, Inc., writing Linux and FreeBSD drivers and doing Open Source evangelism.

Watson Research Center Checkpoints of GUI-based Applications Victor C. Zandy and Barton P. Miller, University of Wisconsin CUP: Controlled Update Propagation in Peer-to-Peer Networks Mema Roussopoulos and Mary Baker, Stanford University	INVITED TALKS The NPACI Rocks Cluster Toolkit: Breaking the Myth of Homogeneous Clusters Philip Papadopoulos, San Diego Supercomputer Center The Rocks toolkit allows users to stand up small, medium, and large-scale x86 and IA64 clusters in a short period of time. It starts with the assumption that clusters are heterogeneous in both hardware and functionality. Rocks decomposes the configuration of nodes (termed appliances) into small, reusable building blocks that include both software package and configuration information. Using a graph construction, shared configuration information across appliance types can be easily expressed. Utilizing the extensive hardware probing of modern OS installers, heterogeneous nodes become no harder to support than assumed homogeneous nodes. Installation and reinstallation performance figures will be given.	FREENIX TRACK File Systems Session Chair: Chuck Lever, Network Appliance Awarded Best Paper!

GENERAL TRACK Security Mechanisms The Design of the OpenBSD Cryptographic Framework Angelos D. Keromytis, Columbia University; Jason L. Wright and Theo de Raadt, OpenBSD Project NCryptfs: A Secure and Convenient Cryptographic File System Charles P. Wright, Michael C. Martino, and Erez Zadok, Stony Brook University A Binary Rewriting Defense Against Stack-based Buffer Overflow Attacks Manish Prasad and Tzi-cker Chiueh, Stony Brook University	INVITED TALKS Alternative Top-Level Domains (a.k.a. The Game of the Name) Steve Hotz, New.net Naming is a fundamental concept for systems architects, a critical decision for marketers, and a requirement for operating networked computers. Quite simply, we care about names. Consequently, it is no surprise that control of the DNS, the primary Internet namespace, is a morass of highly charged technical, financial, legal, and political issues. This talk discusses issues surrounding alternative top-level domains, and the somewhat controversial approach New.net has taken to expanding the operational DNS namespace.

Work-in-Progress Reports 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 usenix03wips@usenix.org. 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. Work-in-Progress reports are five-minute presentations; the time limit will be strictly enforced.
