Thèse De Doctorat De Sorbonne Université Spécialité InformatiqueThis thesis advances the field of differential based cryptanalysis by introducing severalinnovative improvements. The first contribution focuses on enhancing the efficiencyof differential-linear attacks through precise control of the sampling set, resulting in anotable increase in correlation. Subsequently, a step by step description of a differentialattack on the full version of the cryptographic primitive SPEEDY-7-192 is outlined,hence exhibiting the application of numerous refined improvements. Furthermore, a newtechnique called differential-MITM cryptanalysis is introduced, alongside its practicalapplication to SKINNY-128-184. Finally, an adaptation of impossible differenti...
