Camellia, a 128–bit block cipher which has been accepted by ISO/IEC as an international standard, is increasingly being used in many cryptographic applications. In this paper, using the redundancy in the key schedule and accelerating the filtration of wrong pairs, we present a new impossible differential attack to reduced–round Camellia. By this attack 12–round Camellia–128 without FL/FL−1 functions and whitening is breakable with a total complexity of about 2 encryptions and 2 chosen… CONTINUE READING
