| Abstract(in English) | This paper theoretically investigates how the probabilistic counting method can be applied to linear cryptanalysis for LOKI91. We show our probabilistic counting method with 2^<21> counters breaks reduced 4, 6, 7, 9, 10, 12 rounds LOKI91 with only 6% known plaintexts which are required using the original linear cryptanalysis shown in [Tokita, Sorimachi, Matsui, -ASIACRYPT'94, LNCS 917, Springer-Verlag, 1994.]. Furthermore, our attack for 4-round LOKI91 needs as much as almost a quarter of known plaintexts which was required in the recent multiple linear cryptanalysis with non-linear approximations [Knudsen, Robshaw, -EUROCRYPT'96,LNCS 1070, Springer-Verlag, 1996.]. |
