Title:
Improved Differential-Linear Attacks with Applications to ARX Ciphers
Authors: Christof Beierle, Gregor Leander, Yosuke Todo
Abstract:We present several improvements to the framework of differential-linear attacks with a special focus on ARX ciphers. As a demonstration of their impact, we apply them to Chaskey and ChaCha and we are able to significantly improve upon the best attacks published so far.
