Improving the higher order differential attack and cryptanalysis of the KN cipher [PDF]
ISW, 1998 Since the proposal of differential cryptanalysis and linear cryptanalysis in 1991 and 1993, respectively, the resistance to these cryptanalyses have been studied for many cryptosystems. Moreover, some block ciphers with provable security against differential and linear cryptanalysis have been proposed.

Higher order differential cryptanalysis framework and its applications
International Conference on Information Science and Technology, 2011 In this paper, we introduce a higher order differential cryptanalysis framework based on higher order derivatives. We show the previous attacks, higher order differential attack(HODA), algebraic IV differential attack(AIDA), Cube Attack, Cube Tester and bitwise higher order differential attack(BHODA) are all theoretically based on higher order ...

On MISTY1 Higher Order Differential Cryptanalysis
International Conference on Information Security and Cryptology, 2001 MISTY1 is a block cipher whose design relies on an assertion of provable security against linear and differential cryptanalysis. Yet, a simplified and round reduced version of MISTY1 that does not alter the security provability can be attacked with higher order differential cryptanalysis.

Bitwise Higher Order Differential Cryptanalysis
International Conference on Trusted Systems, 2010 This paper attempts to utilize the ideas of higher order differential cryptanalysis to investigate Boolean algebra based block ciphers. The theoretical foundation is built for later research, and two kinds of distinguishing attacks are proposed. The prerequisites of the attacks are also presented and proved, and an efficient algorithm is introduced to ...

Linear Cryptanalysis on SPECTR-H64 with Higher Order Differential Property
Mathematical Methods, Models, and Architectures for Network Security Systems, 2003 In this paper, we find linear equations of SPECTR-H64 using the property of controlled permutation boxes. Also, we construct the fourth-order differential structure using the property that the algebraic degree of the function G is 3, which is the only non-linear part of SPECTR-H64. These linear equations and structures enable us to attack the reduced 6

Higher Order Derivatives and Differential Cryptanalysis
, 1994 High-order derivatives of multi-variable functions are studied in this paper as a natural generalization of the basic concept used in differential cryptanalysis. Possible applications of such derivatives in cryptology are discussed.

A New Higher Order Differential of RAGHAV
2022 Tenth International Symposium on Computing and Networking Workshops (CANDARW), 2022RAGHAV is a 64-bit block cipher proposed by Bansod in 2021. It supports 80-, and 128-bit secret keys. The designer evaluated its security against typical attack, such as differential cryptanalysis, linear cryptanalysis, and so on.
