Security Analysis of Lightweight IoT Cipher: Chaskey
Cryptography, 2020 This paper presents the differential cryptanalysis of ARX based cipher Chaskey using tree search based heuristic approach. ARX algorithms are suitable for resource-constrained devices such as IoT and very resistant to standard cryptanalysis such as ...

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 ...

Related-Key Linear Cryptanalysis [PDF]
2006 IEEE International Symposium on Information Theory, 2006 A coding theory framework for related-key linear cryptanalytic attacks on block ciphers is presented. It treats linear cryptanalysis as communication over a low capacity channel, and a related key attack (RKA) as a concatenated code. It is used to show that an RKA, using n related keys generated from k independent ones, can improve the amortized cost ?

Multidimensional Linear Cryptanalysis of Feistel Ciphers
IACR Transactions on Symmetric Cryptology, 2023 This paper presents new generic attacks on Feistel ciphers that incorporate the key addition at the input of the non-invertible round function only.

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.

Dianzi Jishu Yingyong, 2021 NBC is a family of block ciphers using Generalized Feistel structure, designed by Xu Hong et al. There are three block and key sizes,i.e.,128/128, 128/256 and 256/256. A 16-bit Sbox is involved in the cipher as the non-linear component.
