We have analysed tweakable block cipher Scream which is used by cipher SCREAM, with the techniques linear cryptanalysis, differential cryptanalysis and related key cryptanalysis. Tweakable block cipher Scream is already analysed with linear, differential-linear and impossible differential cryptanalysis in our previous paper. In this paper we extend our work by adding related key attack along with the differential-linear attack.
