1. A method for creating an enhanced RFID tag comprising:
- proximately co-locating a longer range RFID tag and a relatively shorter range credential in the same container; and
cryptographically binding the longer range RFID tag to the shorter range credential by storing, on the longer range tag, signed data including indicia of the shorter range tag;
wherein the longer range RFID tag requires authorization via an authentication server to grant access to data stored in the enhanced RFID tag.

Abstract
A method for creating an enhanced RFID tag. A longer range RFID tag and a relatively shorter range credential are proximately co-located in the same container. The longer range RFID tag is cryptographically bound to the shorter range credential by storing, on the longer range tag, signed data which includes indicia of the shorter range tag. The longer range RFID tag requires authorization via an authentication server to grant access to data stored in the enhanced RFID tag.

10. A method for creating an enhanced RFID tag comprising:
-
proximately co-locating a longer range RFID tag and a shorter range credential in the same container; cryptographically binding a longer range RFID tag to the shorter range credential by storing, on the longer range tag, signed data including indicia of the shorter range tag; encrypting the data on the longer range tag with a key derived from at least one characteristic selected from the set of characteristics consisting of an anticollision ID, physical characteristics of the enhanced tag, characteristics of the tag bearer, and characteristics of an item to which the enhanced tag is affixed; re-encrypting the longer range tag with a different IV each time the longer range tag is read to effectively change the contents thereof; authenticating the enhanced tag by including and updating a nonce in the signed data; and updating the nonce by an RFID reader and storing the nonce in a database at a given authority. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
