Abstract
A Radio Frequency Identification (RFID) tag integrated circuit (IC) stores a subportion of a digital signature and a subportion indicator that may be used to authenticate the IC, a tag including the IC, and/or an item associated with the tag. The subportion of the digital signature is generated, at least in part, by applying a cryptographic function to an identifier associated with the IC, the tag, and/or the item.
