Cryptanalysis of the Speck Family of Block Ciphers

Farzaneh Abed, Eik List, Stefan Lucks, and Jakob Wenzel

Abstract

Simon and Speck are two families of ultra-lightweight block ciphers which were announced by the U.S. National Security Agency in June 2013. This paper presents differential and rectangle attacks for almost all members of the Speck family of ciphers, where we target up to 11/22, 12/23, 15/27, 15/29, and 18/34 rounds of the 32-, 48-, 64-, 96-, and 128-bit version, respectively.
