Cryptanalysis of the Speck Family of Block Ciphers.
TLDR
This paper presents differential and rectangle attacks for almost all members of the Speck family of ciphers, where 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.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.read more

The LED block cipher
TL;DR: This work considers the resistance of ciphers, and LED in particular, to related-key attacks, and is able to derive simple yet interesting AES-like security proofs for LED regarding related- or single- key attacks.

KATAN and KTANTAN -- A Family of Small and Efficient Hardware-Oriented Block Ciphers
TL;DR: A new family of very efficient hardware oriented block ciphers divided into two flavors, which is more compact in hardware, as the key is burnt into the device (and cannot be changed), and achieves encryption speed of 12.5 KBit/sec.
