We propose a new 64-bit blockcipher Piccolo supporting 80 and 128-bit keys. Adopting several novel design and implementation techniques, Piccolo achieves both high security and notably compact implementation in hardware. We show that Piccolo offers a ...
Piccolo is a lightweight block cipher, with a fixed 64-bit block size and variable key length 80- or 128-bit, which was proposed at CHES 2011. The iterative structure of Piccolo is a variant of Generalized Feistel Network. The transformation utilizing ...
Piccolo is a lightweight block cipher designed by Sony Corporation and published in CHES 2011. It inherits the Generalized Feistel Network GFN structure and operates on a 64-bit state. It has two versions; Piccolo-80 and Piccolo-128 with 80-bit and 128-...
