| 英文摘要 | The vet all structure is one of the most, important, properties of block ciphers At present, the most common structures include Feistel structure. SP structure. MISTY structure, L-M structure and Generalized Feistel structure In 29, Choy et, al proposed a new structure called GF-NLFSR. (Generalized Feistel-NonLinear Feedback Shift, Register). and designed a new block cipher called Four-Cell which is based on the 4-cell GF-NLFSR. In this paper, we first, study properties of the n-cell GF-NLFSR structure, and prove that, for an n-cell GF-NLFSR, there exists an (n(2) + n - 2) rounds impossible differential Then we present an impossible differential attack on the full 25-round Four-Cell using this kind of 18-round impossible differential distinguished together with differential cryptanalysis technique. The data complexity of our attack is 2(111) (5) and the tune complexity is less than 2(123 5) encryptions In addition: we expect, the attack to be More efficient when the relations between different, round subkeys can be exploited by taking the key schedule algorithm into consideration |
