• 8/15/2006 - Talk - Melanie Rieback
  Melanie Rieback from Vrije University presenting talk "RFID Guardian: A Personal Platform for RFID Privacy Management," San Diego Supercomputer Center Room 408 at 2pm This talk will present the design and implementation of the RFID Guardian, the first-ever unified platform for RFID security and privacy administration. Radio Frequency Identification (RFID) tags are remotely-powered data carriers, that are often touted as "computers of the future", that bring intelligence to our homes and offices, optimize our supply chains, and keep a watchful eye on our pets, livestock, and kids. The RFID Guardian resembles an "RFID firewall", enabling individuals to monitor and control access to their RFID tags by combining a standard-issue RFID reader with unique RFID tag emulation capabilities. Our system provides a platform for coordinated usage of RFID security mechanisms, offering fine-grained control over RFID-based auditing, key management, access control, and authentication capabilities. We have prototyped the RFID Guardian using off-the-shelf components; compatible with the ISO 15693/14443 (13.56 MHz) RFID standards, it performs RFID tag emulation and selective RFID tag jamming. The presentation will conclude with a live demonstration of the RFID Guardian.

• 10/25/2006 - Talk - Arvind Krishnamurthy
  Arvind Krishnamurthy presents talk "Towards an Information Plane for Internet Services" at the UCSD CSE building room 4109 at 12:00 p.m.
  
  The Internet by design is opaque to its applications, providing best effort packet delivery with little or no information about the likely performance or reliability characteristics of different paths. While this is a reasonable design for simple client-server applications, many emerging large-scale distributed services depend on richer information about the state of the network. The Internet also can benefit from more information about itself, e.g., ISPs can monitor the global state of the Internet for reachability and root cause analysis, routing instability, and onset of DDoS attacks. To address such needs, we develop an Information Plane (iPlane) that continuously performs measurements to generate and maintain an annotated map of the Internet with a rich set of link and router attributes. iPlane then uses structural information such as the router-level topology and autonomous system topology to predict paths and their properties between arbitrary nodes in the Internet. We present preliminary results that demonstrate the feasibility of building the Information Plane and its utility in optimizing representative overlay services in use today.
  
  
• 10/30/2006 - Talk - Allen Downey
  Allen Downey presents talk "Changepoint detection in network measurements" at the San Diego Supercomputer Center Auditorium on Monday, October 30, 2006 at 11:00 a.m.
  
  

  Time-series measurements of network performance are often characterized by periods of statistical stationarity punctuated by abrupt changes. Identifying these changepoints is useful for understanding and predicting network behavior.

  I will present a novel Bayesian framework for estimating the probability of a changepoint in a time series, and demonstrate its use on several example problems. I will also show how the framework can be applied to "online" changepoint detection, and compare it to GLR, a standard technique for this problem.

  This talk will include a general introduction to changepoint problems and Bayesian statistics. This project is work in progress; I will present some of the problems I am currently dealing with, and I would be interested in talking to the audience about possible applications of these techniques.

  "Building the next generation Internet architecture in Canada" at San Diego Supercomputer Center Auditorium at 10:00 a.m.
  
  

  Around the world there are several initiatives to develop the next generation canonical Internet network architecture. These initiatives are being driven by at least four significant developments, first: the concern that the current Internet is ossifying and that it is increasingly difficult to deploy new architectures, secondly: the trend towards a two tiered Internet where the owners of the network control access by third partners, thirdly: the trend for more users to own, control and manage their own network resources and fourthly: the demand by big science and large enterprises to have dedicated network resources for the data flows generated by their high-end applications. One approach to address all these issues is being developed in Canada by CANARIE where a key assumption is that there is no longer need for a canonical network architecture.

  Instead, the User Controlled LightPath (UCLP) software developed by CANARIE and its partners allows users to define their own packet or switched based network architecture including topology, routing, virtual routers, switches, virtual machines and protocols based on the concept of many separate, concurrent and independently managed Articulated Private Networks (APN) operating on top of one or more network substrates across different ownership domains. APNs can be considered as a next generation Virtual Private Network where a user can create a complex network multi-domain topology by binding together layer 1 through 3 network links, computers, time slices and virtual or real routing and/or switching nodes. This capability of UCLP is realized by representing all such network element, devices and links as web services, and by using web services workflow as the tool to allow the user to bind together their various web services to create a long lived APN instantiation. With web services workflow the user also has the ability to offer all, or portions of their APN as a web service (or set of services) in its own right to other downstream users.

• 11/9/2006 - Talk - Rene L. Cruz
  "Sharing with your neighbors: the case for cooperation in broadband access networks" at the San Diego Supercomputer Center Auditorium on Thursday, November 9, 2006 at 11:15 am. For questions regarding this talk, please send a message to info@caida.org
  
  

  The advent of low cost wireless communication technology has driven the explosion of user owned and managed wireless data networks, specifically WiFi local area networks. Ironically, though the Internet itself was originally driven by a culture of cooperation and open-ness, managers (users) of WiFi networks are increasingly motivated to "close" their networks to prevent unauthorized use of their networks. In this talk, I nevertheless argue that there is a large possible upside for cooperation in broadband access networks, and that a high speed communication link that directly connects homes in a neighborhood has considerable value. This creates a unique and compelling application for ad-hoc mesh networks.

  I will describe a technology originally developed at UCSD which exploits the inherent burstiness of Internet access traffic. A high speed local area network in a neighborhood is established in order to facilitate the dynamic pooling and sharing of the aggregate access bandwidth available. This can result in a much larger available peak bandwidth to each individual user in the neighborhood, as well as increased reliability, in a cost effective manner.

  This technology has been further developed at Mushroom Networks, Inc., and I will discuss a series of related products that are planned for release in the near future. I will describe how these products relate to existing and planned municipal WiFi networks, as well as planned trial deployments in the San Diego area. I hope to identify possible areas of future collaboration with members of the audience.
