Abstract
A method for provisioning security for an RFID tag. Initially, a random new tag ID is generated, and a new master key is generated based on an existing master key. Encrypted user data to be placed on the tag is generated utilizing the new tag ID as an IV and the new master key as input to an encryption algorithm. The new tag ID and the encrypted user data are then written to the tag.
