1 Scope This document defines a coding suite based on an exclusive or (XOR) operation for the ISO/IEC 18000 air interfaces standards for radio frequency identification (RFID) systems. In particular, it specifies the use of XOR as a basic way to hide plain data in the identity authentication and secure communication procedures. The coding suite is defined in alignment with existing air interfaces. This document defines various authentication methods and methods of use for the XOR. A tag and an interrogator may support one, a subset, or all of the specified options, clearly stating what is supported.
