RFID leaks Privacy Information through DNS, Alice Cryptology
Highly recommended - Karsten Nohl (PhD candidate at the University of Virginia, Computer Science), RFID Privacy, Old Threats and New Attacks. Hope 2006. Alice cryptography is the example here, and every minute is valuable - how RFID are related to databases, and how to detect location information through cashes in Domain Server requests. Scalability to reality in terms of billions of tags, and the tree of secrets.
Faraday cages are mentioned -
"A Faraday cage or Faraday shield is an enclosure formed by conducting material, or by a mesh of such material. Such an enclosure blocks out external static electrical fields.
RFID passport and credit card shielding sleeves are small, portable Faraday cages."

As is ONS -
Object Naming Service (ONS)
"mechanism that leverages Domain Name System (DNS) to discover information about a product and related services from the Electronic Product Code (EPC). It is a component of the EPCglobal Network.
It is published by the EPCglobal board. Version 1.0 of the specification was ratified by the board in October, 2005."
