(2004); to ratou tātari whakaaro e taea te whakamahi tata rārangi maha ki te whakaiti i te whakaritenga raraunga o te whakaeke i te iti rawa i te take o 4 (arā, 241 hei utu o 243). Ka taea te whiriwhiri i te whakaiti i te matatini i roto i te raraunga i roto i te rerekē tūturu-plaintext o te cryptanalysis rārangi (Matsui, 1994), a ko te tuatahi whakamātautau ki te whakatau i te matatini o te cryptanalysis).
