DESCRIPTION:*Slides "available":http://www.cl.cam.ac.uk/research/srg/opera
 /meetings/attachments/privacy-preserving_evans_2008_05_20.pdf .*\n\n*Abstr
 act:*\n\nThis talk describes one method of achieving communication privacy
  for ubiquitous systems and presents some preliminary performance results.
 \nMore specifically\, we (i) describe the difference between data privacy 
 and communication privacy and outline why both are important in ubiquitous
  computing\; (ii) describe how to modify Tor\, an anonymous communication 
 framework\, to provide anonymous datagram communication suitable for use i
 n ubiquitous systems\; and (iii) test and evaluate the performance of our 
 proposal with reference to an example citywide sensor\nnetwork. We find th
 at the system offers ubiquitous applications a low latency communication c
 hannel with reasonable privacy properties and that one pays surprisingly l
 ittle for the benefits of the Tor infrastructure.\n\n*Bio:*\n\nDavid Evans
  is a Research Associate attached to the TIME-EACM project\, examining iss
 ues of security and privacy in transport monitoring middleware and applica
 tions.\n\nHe holds a PhD from the University of Waterloo in Waterloo\, Ont
 ario\, Canada\, where he explored resource management strategies for the d
 elivery of rapidly changing\, frequently requested information.\n\nHe has 
 also worked on software infrastructures for unobtrusive monitoring of frai
 l individuals\, and with the IBM Centre for Advanced Studies on web system
  scalability and data centre resource provisioning.\n\nHis masters researc
 h covered digital rights management.\n\nHis research interests include per
 formance modelling and analysis of distributed and operating systems\, pri
 vacy and trust\, and novel applications for low-overhead virtualisation.\n
