TLDR
The U.S. National Security Agency developed the Simon and Speck families of lightweight block ciphers as an aid for securing applications in very constrained environments where AES may not be suitable.Abstract:
The U.S. National Security Agency (NSA) developed the Simon and Speck families of lightweight block ciphers as an aid for securing applications in very constrained environments where AES may not be suitable. This paper summarizes the algorithms, their design rationale, along with current cryptanalysis and implementation results.read more

The SKINNY Family of Block Ciphers and Its Low-Latency Variant MANTIS
Christof Beierle,Jérémy Jean,Stefan Kölbl,Gregor Leander,Amir Moradi,Thomas Peyrin,Yu Sasaki,Pascal Sasdrich,Siang Meng Sim +8 more
TL;DR: A new tweakable block cipher family SKINNY is presented, whose goal is to compete with NSA recent design SIMON in terms of hardware/software performances, while proving in addition much stronger security guarantees with regards to differential/linear attacks.

Midori: A Block Cipher for Low Energy
Subhadeep Banik,Andrey Bogdanov,Takanori Isobe,Kyoji Shibutani,Harunaga Hiwatari,Toru Akishita,Francesco Regazzoni +6 more
TL;DR: This paper presents the block cipher Midorii¾?, the Japanese translation for the word Green, that is optimized with respect to the energy consumed by the circuit per bt in encryption or decryption operation, and proposes two energy-efficient block ciphers Midori128i½?and Midori64i¼?

RECTANGLE: a bit-slice lightweight block cipher suitable for multiple platforms
TL;DR: Due to the careful selection of the S-box and the asymmetric design of the permutation layer, RECTANGLE achieves a very good security-performance tradeoff and achieves avery competitive software speed among the existing lightweight block ciphers due to its bit-slice style.

PRESENT: An Ultra-Lightweight Block Cipher
Andrey Bogdanov,Lars R. Knudsen,Gregor Leander,Christof Paar,Axel Poschmann,Matthew Robshaw,Yannick Seurin,C. Vikkelsoe +7 more
TL;DR: In this paper, the authors describe an ultra-lightweight block cipher, present, which is suitable for extremely constrained environments such as RFID tags and sensor networks, but it is not suitable for very large networks such as sensor networks.

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.

Authenticating pervasive devices with human protocols
Ari Juels,Stephen A. Weis +1 more
TL;DR: This paper analyzes a particular human-to-computer authentication protocol designed by Hopper and Blum (HB), and shows it to be practical for low-cost pervasive devices, and proves the security of the HB+ protocol against active adversaries based on the hardness of the Learning Parity with Noise (LPN) problem.

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.
