Camellia is a block cipher cooperatively designed by NTT and Mitsubshi Electric Corporation and submitted to NESSIE. In this
paper, we present truncated differential cryptanalysis of modified Camellia reduced to 7 and 8 rounds. For modified Camellia
with 7 rounds we can find 8-bit key with 3 · 281 plaintexts and for modified Camellia with 8 rounds we can find 16-bit key with 3 · 282 plaintexts.
