Bit-pattern Based Integral Attack on ICEBERG
Yuechuan Wei · 2015
Integral attack is one of the most effective attack against block ciphers. However, traditional integral attack based on byte or word is not available for a bit-oriented cipher. Z'aba et al. introduced a technique named Bit-pattern based integral attack to address this issue. This new type of integral attack traces the propagation of the plaintext structure at bit-level to obtain the property and verify key guesses. In this paper, the bit-pattern based integral attack is applied to ICEBERG - a block cipher efficient in reconfigurable hard-ware. The result shows that 3, 4 and 5 rounds ICEBERG are not immune to this attack. All attacks presented in this paper manage to recover the full subkeys of the final round.
