Improved automatic search of impossible differentials for camellia with FL/FL-1 layers

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 n...

Description
Summary:	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.
