Some cryptanalytic results on Lizard
Subhadeep Banik and Takanori Isobe
Abstract
Lizard is a lightweight stream cipher proposed by Hamann, Krause and Meier in IACR ToSC 2017. It has a Grain-like structure with two state registers of size 90 and 31 bits. The cipher uses a 120 bit Secret Key and a 64 bit IV. The authors claim that Lizard provides 80 bit security against key recovery attacks and a 60-bit security against distinguishing attacks. In this paper, we present an assortment of results and observations on Lizard. First, we show that by doing
