1. A method to provide a cryptographic protocol comprising:

  • authentication based on a use of a private key of a low-processing-power system (LPPS);

    privacy to protect a tag identifier (tag ID) so that an unauthorized party cannot learn the identifier for the tag; and

    untraceability to ensure that a different value is returned in response to a challenge, so a reader cannot identify the LPPS by the response.
