Integral and Impossible Differential Cryptanalysis of RC6

2018
The block cipher RC6 is one of the finalists of the five candidates of AES for its security, simplicity and easy soft-hardware implementation. In view of its importance, the resistance of RC6 against integral cryptanalysis and impossible differential cryptanalysis is evaluated in this paper.

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

Note on Impossible Differential Attacks

2016
While impossible differential cryptanalysis is a well-known and popular cryptanalytic method, errors in the analysis are often discovered and many papers in the literature present flaws. Wishing to solve that, Boura et al.i¾?[1] presented at ASIACRYPT'14 a generic vision of impossible differential attacks with the aim of simplifying and helping the ...

Impossible Differential Cryptanalysis on Tweaked E2

2012
E2, a 128-bit block cipher, is an AES candidate designed and submitted by NTT corporation. It employs a Feistel structure as global structure and 2-layer Substitution-Permutation Network structure in round function. The conservative structure makes E2 immune to kinds of current cryptanalysis.

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

Differential and Impossible Differential Related-Key Attacks on Hierocrypt-L1

2014
Hierocrypt-L1 is one of the Japanese e-Government Recommended Ciphers listed by CRYPTREC in 2003, and its security was reconfirmed as secure by CRYPTREC in 2013. In this paper we first find differential characteristics with probability 1 in the key scheduling of Hierocrypt-L1.

Improbable Differential from Impossible Differential: On the Validity of the Model

2013
Differentials with low probability are used in improbable differential cryptanalysis to distinguish a cipher from a random permutation. Due to large diffusion, finding such differentials for actual ciphers remains a challenging task. At Indocrypt 2010, Tezcan proposed a method to derive improbable differential distinguishers from impossible ...
