I am interested in knowing if RFID can be a technology for machine-to-machine authentication over long-distance networks. Can the RF signal be broadcast over the Internet to authenticate a server trying to access another Internet-based, RFID-enabled Web server machine? Thanks in advance for your reply.



Dear Joe:

Interesting question. This would not seem to be a viable use of RFID. I guess you could build an RFID reader into every server, and have an unclonable tag affixed to the motherboard. A remote machine could first access the interrogator and have it read a tag on the motherboard and then, if it gets the right ID, initiate communication with the machine. Obviously, you would need to know the machine's RFID tag number in advance. I don't think, however, that this would enhance security. The tag could be removed from one machine and placed in another. It would seem to me that if two machines were able to connect via a network, they would not need RFID to identify one another.

Perhaps our readers will have a different view of this.
