  3. Abstract:
  4. Biclique attack is one of the most recent methods for cryptanalysis of block ciphers. In this paper, we present a new biclique attack on the full round of the lightweight block cipher CLEFIA-128. We obtained 2127.44 for computational complexity while the data complexity is 264 and memory complexity is 27. To the best of our knowledge, it is the first biclique attack on the full CLEFIA-128 lightweight block cipher. Also, we show that MITM attack in the way of using partial matching with precomputation and recomputation technique can reduce the data complexity of the attack to only 2 known plaintext-ciphertext pairs
