Differential-Linear Cryptanalysis [PDF]
, 2007 This paper introduces a new chosen text attack on iterated cryptosystems, such as the Data Encryption Standard (DES). The attack is very efficient for 8-round DES,2 recovering 10 bits of key with 80% probability of success using only 512 chosen plaintexts. The probability of success increases to 95% using 768 chosen plaintexts.

Related-Key Differential Cryptanalysis of the Reduced-Round Block Cipher GIFT
IEEE Access, 2019 GIFT is a lightweight block cipher that was proposed by Banik et al. at CHES 2017, which is said to be a direct improvement over PRESENT since “that provides a much increased efficiency in all domains (smaller and faster)” and improves the ...

Cryptanalysis of two chaotic encryption schemes based on circular bit shift and XOR operations [PDF]
, 2007 Recently two encryption schemes were proposed by combining circular bit shift and XOR operations, under the control of a pseudorandom bit sequence (PRBS) generated from a chaotic system. This paper studies the security of these two encryption schemes and

Quantum differential cryptanalysis
Journal of Computer Virology and Hacking Techniques, 2021 The work is devoted to the study quantum versions of the differential cryptanalysis based on using a combination of the quantum minimum/maximum search algorithm and the quantum counting algorithm. We have estimated the complexity and the required resources for applying the quantum differential and quantum linear cryptanalysis to searching round keys of

Influence of Non-Linearity on Selected Cryptographic Criteria of 8x8 S-Boxes
Acta Informatica Pragensia, 2017 The article defines standard criteria used to characterize the cryptographic quality of the S box: regularity, non linearity, autocorrelation, avalanche and immunity against differential cryptanalysis.

On the Complexity of Impossible Differential Cryptanalysis [PDF]
Security and Communication Networks, 2018 While impossible differential attack is one of the most well-known and familiar techniques for symmetric-key cryptanalysts, its subtlety and complicacy make the construction and verification of such attacks difficult and error-prone. We introduce a new set of notations for impossible differential analysis.

Cryptanalysis of an MPEG-Video Encryption Scheme Based on Secret Huffman Tables [PDF]
, 2007 This paper studies the security of a recently-proposed MPEG-video encryption scheme based on secret Huffman tables. Our cryptanalysis shows that: 1) the key space of the encryption scheme is not sufficiently large against divide-and-conquer (DAC) attack ...

Differential Cryptanalysis of Q [PDF]
, 2002 Q is a block cipher based on Rijndael and Serpent, which was submitted as a candidate to the NESSIE project by Leslie McBride.The submission document of Q describes 12 one-round iterative characteristics with probability 2-18 each. On 7 rounds these characteristics have probability 2-126, and the author of Q claims that these are the best 7- round ...

Differential Meet-In-The-Middle Cryptanalysis
, 2023 In this paper we introduce the differential meet-in-the-middle framework, a new cryptanalysis technique for symmetric primitives. Our new cryptanalysis method combines techniques from both meet-in-themiddle and differential cryptanalysis. As such, the introduced technique can be seen as a way of extending meet-in-the-middle attacks and their variants ...
