摘　　要：Camellia is an inte.rnational standard adopted by ISO/IEC and is recommended by CRYPTREC and NESSIE project. Wu et al. [1] presented an effective tool to search truncated impossible differentials for word-oriented block ciphers with bijective Sboxes. However, their nlethod only adopted Sbox as the nonlinear part and cannot be applied to Camellia with FL/FL 1 layers.Camellia is an inte.rnational standard adopted by ISO/IEC and is recommended by CRYPTREC and NESSIE project.
