Title:
A Note on the Bias of Rotational Differential-Linear Distinguishers

Authors: Yunwen Liu, Zhongfeng Niu, Siwei Sun, Chao Li, Lei Hu

Abstract:

This note solves the open problem of finding a closed formula for the bias of a rotational differential-linear distinguisher proposed in IACR ePrint 2021/189 (EUROCRYPT 2021), completely generalizing the results on ordinary differential-linear distinguishers due to Blondeau, Leander, and Nyberg (JoC 2017) to the case of rotational differential-linear distinguishers.
