Applying Internet-level security to RFID is something that has not gone very far, according to this RFID Update story about the anticipated rollout. NeoCatena Networks is developing RF-Wall, an appliance to be installed between RFID readers or controllers and middleware servers, edge servers or host applications in networked RFID systems. The product acts as a firewall that authenticates RFID tags prior to allowing their data to pass into enterprise systems and also scans input to detect and block malware. RF-Wall works by using the unique tag ID to create a digital signature.
NeoCatena Networks has in the wings a product designed to stop fraudulent or bad tag data from getting into the system from the supply chain.
