Abstract

Abstract : Rotational/Rotational-XOR differential-linear attack is a kind of powerful attack on ARX primitives. In this paper, we analyse the message authentication code algorithm—Chaskey—by using rotational differential-linear attack and using partitioning technique for key recovery. We presentthe results of distinguishing attack under weak-key and related-key settingswith correlation 2 − 55.636 for 9-round Chaskey. This is for the first time rotational differential-linear distinguisher has been used to analyse Chaskey. It is concluded that Chaskey can resist against rotational differential-linear attack.
