An improved impossible differential cryptanalysis of Zodiac

Journal of Systems and Software, 2010
In 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, 2019
The 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 DIFFERENTIAL CRYPTANALYSIS OF MINI-AES

Cryptologia, 2003
Impossible differential cryptanalysis is one of the cryptanalysis methods that are applicable to the new Advanced Encryption Standard (AES). In this paper, we present an introduction to the method by applying it on Mini-AES, the mini version of the AES published in Cryptologia recently.

Impossible Differential Cryptanalysis of Reduced-Round LBlock [PDF]

Lecture Notes in Computer Science, 2012
In this paper, we improve the impossible differential attack on 20-round LBlock given in the design paper of the LBlock cipher. Using relations between the round keys we attack on 21-round and 22-round LBlock with a complexity of 269.5 and 279.28 encryptions respectively.

Impossible differential cryptanalysis on cipher E2

Concurrency and Computation: Practice and Experience, 2013
SUMMARYE2, 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.

Improved Impossible Differential Cryptanalysis of SMS4

2012 Eighth International Conference on Computational Intelligence and Security, 2012
The SMS4 is the first commercial block cipher published by Chinese government. It's a 32-round block cipher encrypted by 128-bit keys. By analyzing the changes of the difference between input and output pairs in each round, this paper presents a new impossible differential path of the 14- round SMS4.
