Improved meet-in-the-middle attacks on reduced-round Piccolo

Piccolo is a lightweight block cipher that adopts a generalized Feistel network structure with 4 branches, each of which is 16 bit long. The key length is 80 or 128 bit, denoted by Piccolo-80 and Piccolo- 128, respectively. In this paper, we mounted meet-in-the-middle attacks on 14-round Piccolo-80...
