An improved impossible differential cryptanalysis of Zodiac
Journal of Systems and Software, 2010In this paper, we introduce a new impossible differential cryptanalysis of Zodiac that is considerably more effective than the one in the previous work (Hong et al., 2002). Using two new 13-round impossible differential characteristics and the early abort technique, this 3R-Attack breaks 128-bit key full-round Zodiac with complexity less than 2^7^1^.^3

Impossible Differential Cryptanalysis of SPECK
Communications in Computer and Information Science, 2019The security of SPECK under impossible differential cryptanalysis is studied. Based on multiple 6-round impossible differential distinguishers and combined with the divide-and-conquer attack and time-and-memory tradeoff, the improved 10-round impossible differential cryptanalysis of SPECK32/64 and SPECK48/96 is presented by adding one round forward and

Impossible Differentials of SPN Ciphers
2017An upper bound of the length of impossible differentials for an SPN structure was presented at EUROCRYPT 2016. This paper mainly focuses on the lengths of impossible differentials for two specific SPN structures. The details of the S-boxes could be exploited to construct longer impossible differentials for ciphers adopting these structures.

Impossible differential attack on Simpira v2
Science China Information Sciences, 2017Simpira v2 is a family of cryptographic permutations proposed at ASIACRYPT 2016, and can be used to construct high throughput block ciphers by using the Even-Mansour construction, permutation-based hashing, and wide-block authenticated encryption. This paper shows a 9-round impossible differential of Simpira-4. To the best of our knowledge, this is the

Improved Impossible Differentials on Twofish
2000Twofish is one of the finalists for the Advanced Encryption Standard selection process (AES). The best up-to-date analysis of Twofish was presented by one of its designers, who showed that its complexity on 6-round Twofish with 128-bit keys is 4.6ċ2128 one-round computations.

New Impossible Differential Attacks on AES
2008In this paper we apply impossible differential attacks to reduced round AES. Using various techniques, including the early abort approach and key schedule considerations, we significantly improve previously known attacks due to Bahrak-Aref and Phan. The improvement of these attacks leads to better impossible differential attacks on 7-round AES-128 and ...

Impossible differential cryptanalysis on cipher E2
Concurrency and Computation: Practice and Experience, 2013SUMMARYE2, a block cipher, is an Advanced Encryption Standard candidate designed and submitted by Nippon Telegraph and Telephone Corporation. It employs a Feistel structure as global structure and two‐layer substitution–permutation network structure in round function.

New Impossible Differential Attacks on Camellia
2012Camellia is one of the most worldwide used block ciphers, which has been selected as a standard by ISO/IEC. In this paper, we propose several new 7-round impossible differentials of Camellia with 2 FL/FL−1 layers, which turn out to be the first 7-round impossible differentials with 2 FL/FL−1 layers.
