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.

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.

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.

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.

Databases
Keith Bostic, Sleepycat Software

Keith Bostic was a member of the Berkeley Computer Systems Research Group, where he was the architect of the 2.10BSD release and a principal developer of the 4.4BSD and related releases. He co-designed and implemented the 4.4BSD log-structured filesystem and the Berkeley DB database library. He is currently vice-president of engineering at Sleepycat Software.

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.
