Information technology — Automatic identification and data capture techniques Part 21: Crypto suite SIMON security services for air interface communications (Edition 2, 2026)

Abstract
This document specifies the crypto suite for SIMON for the ISO/IEC 18000 air interface standards for radio frequency identification (RFID) devices.

SIMON is a symmetric block cipher that is parameterized in both its block length and key length. The block/key length options supported in this crypto suite (in bits) are 64/96, 96/96, 64/128, 128/128 and 128/256.

In this document, a Tag and an Interrogator can support one, a subset or all of the specified options, clearly stating what is supported.
