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