Abstract: | Camellia,which is 128-bit block size and supports 128-,192-and 256-bit keys,is one of the NESSTE(New European Schemes for Signatures,Integrity,and Encryption)candidate block ciphers.The Square attack on Camellia is discussed. The results show that the Square method is one of the best attack on Camellia. |
