We observe that when conducting an impossible differential cryptanalysis on Camellia and MISTY1, their round structures allow us to partially determine whether a candidate pair is useful by guessing only a small fraction of the unknown required subkey bits of a relevant round at a time, instead of guessing all of them at once. Taking advantage of the early abort technique, we improve a previous impossible differential attack on 6-round MISTY1 without the FL functions, and present impossible differential cryptanalysis of 11-round Camellia-128 without the FL functions, 13-round Camellia-192 without the FL functions and 14- round Camellia-256 without the FL functions. The presented results are better than any previously published cryptanalytic results on Camellia and MISTY1 without the FL functions.
