Piccolo: an ultra-lightweight blockcipher
TL;DR: Piccolo is one of the competitive ultra-lightweight blockciphers which is suitable for extremely constrained environments such as RFID tags and sensor nodes and its efficiency on the energy consumption which is evaluated by energy per bit is also remarkable.

The 128-Bit Blockcipher CLEFIA (Extended Abstract)
TL;DR: A new 128-bit blockcipher CLEFIA supporting key lengths of 128, 192 and 256 bits, which is compatible with AES is proposed, which achieves enough immunity against known attacks and flexibility for efficient implementation in both hardware and software.

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?
