Addendum to Linear Cryptanalyses of Three AEADs with GIFT-128 as Underlying Primitives
IACR Transactions on Symmetric Cryptology, 2022 In ToSC 2021(2), Sun et al. implemented an automatic search with the Boolean satisfiability problem (SAT) method on GIFT-128 and identified a 19-round linear approximation with the expected linear potential being 2−117.43, which is utilised to launch a ...

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.

Improved conditional differential cryptanalysis [PDF]
Security and Communication Networks, 2014 AbstractIn lightweight cryptographic primitives, non‐linear feedback shift registers (NFSR) are widely used nowadays. At ASIACRYPT 2010, conditional differential cryptanalysis was proposed to analyze NFSR‐based cryptosystems. To get better result, we propose an improved version of this attack.

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 ...

Improbable differential cryptanalysis [PDF]
Proceedings of the 6th International Conference on Security of Information and Networks, 2013 Statistical attacks on block ciphers make use of a property of the cipher so that an event occurs with different probabilities depending on whether or not the correct key is used. For instance, differential cryptanalysis [3] and truncated differential cryptanalysis [5] consider characteristics or differentials which show that a particular output ...

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 ...

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.
