Abstracts of Keynote Lectures
The
UbiSec&Sens Security
Architecture: On the Usage of Homomorphic Encryption Transformations for
Securing Wireless Sensor Networks, Dirk Westhoff (NEC Europe, Heidelberg,
Germany)
It is the objective of this talk to introduce security concepts of the EU FP6 STREP project UbiSec&Sens (Ubiquitous Sensing and Security in the European Homeland). After giving an overview on the various research topics which are addressed in the project in particular, we motivate the need of end-to-end security in wireless sensor networks and compare recent approaches for the encryption of sensed data. The concept of concealed data aggregation (CDA) is introduced and available solutions are analyzed with respect to the contradicting requirements of systems security, energy consumption, and real-time responsiveness. We conclude by showing how such concepts can be applied in synchronous and asynchronous wireless sensor networks.
Traffic
Policing in the Large, Alex C. Snoeren (University of California, San Diego,
USA) [slides]
Today's
cloud-based services integrate globally distributed resources into seamless
computing platforms. Provisioning and accounting
for the resource usage of these Internet-scale applications presents a
challenging technical problem. In
particular, traditional traffic-policing mechanisms function locally and lack
any notion of coordination. In this talk
we consider expanding existing centralized notions of traffic policing to a
distributed context.
In
particular, we will focus on the design and implementation of distributed rate
limiters, which work together to enforce a global rate limit across traffic
aggregates at multiple sites, enabling the coordinated policing of a
cloud-based service's network traffic. A
key challenge is to ensure that congestion-responsive transport-layer flows
behave as if they traversed a single, shared limiter. We present two designs---one general purpose,
and one optimized for TCP---that allow service operators to explicitly trade
off between communication costs and system accuracy, efficiency, and
scalability. In closing, we will discuss
how distributed mechanisms such as these enable the deployment of new classes
of policing policies.
