Cryptography to Ensure RFID Tag Security
Filed in archive Privacy and Security by Anita Campbell on August 12, 2005
privacy consultant and a security company have joined forces on a novel approach to RFID tag security in the retail supply chain.Stephan Engberg of Open Business Innovation has developed certain new RFID privacy enhancing technology that has been licensed by RFIDSec.
The approach calls for enhancing RFID chips with cryptographic functions. The chips then would have two modes: "EPC mode" and "privacy mode."
In the B2B supply chain the chips operate in EPC mode and contain all the data that businesses need.
At the point of sale, the chips are switched to privacy mode and the consumer is in control. The consumer may have the tag be entirely silent and not give out information, or may allow certain data to be transferred in limited situations for warranty claims and so on.
A report on this novel approach to consumer privacy can be found here (PDF).
