AKF: A key alternating Feistel scheme for lightweight cipher designs
We propose a key alternating Feistel scheme, AKF, for lightweight block cipher designs. We analyze the security of AKF. We reintroduce the cipher ITUbee based on AKF where ITUbee is a recent cipher proposed at LightSec2013 conference. We give a detailed differential cryptanalysis of ITUbee.
