A Differential Cryptanalysis of Yen-Chen-Wu Multimedia Cryptography System (MCS) [PDF]
, 2009 At ISCAS'2005, Yen et al. presented a new chaos-based cryptosystem for multimedia transmission named "Multimedia Cryptography System" (MCS). No cryptanalytic results have been reported so far. This paper presents a differential attack to break MCS, which

Provable Security Against a Differential Attack
DAIMI Report Series, 1994 The purpose of this paper is to show that there exist DES-like iterated ciphers, which are provably resistant against differential attacks. The main result on the security of a DES-like cipher with independent round keys is Theorem 1, which gives an upper bound to the probability of <em>s</em>-round differentials, as defined in <em> ...

Chosen Plaintext Combined Attack against SM4 Algorithm
Applied Sciences, 2022 The SM4 algorithm is widely used to ensure the security of data transmission. The traditional chosen plaintext power attacks against SM4 usually need to analyze four rounds power traces in turn to recover the secret key.

Internal collision attack on Maraca [PDF]
, 2009 We present an internal collision attack against the new hash function Maraca which has been submitted to the SHA-3 competition. This attack requires 2^{237} calls to the round function and its complexity is lower than the complexity of the generic ...

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 ...

Doubly Perfect Nonlinear Boolean Permutations
, 2010 Due to implementation constraints the XOR operation is widely used in order to combine plaintext and key bit-strings in secret-key block ciphers. This choice directly induces the classical version of the differential attack by the use of XOR-kind ...

Differential Forgery Attack Against LAC [PDF]
, 2016 LAC is one of the candidates to the CAESAR competition. In this note we present a differential forgery attack on LAC. We show that some differentials have a probability higher than 2^-64, using a collection of characteristics in order to evaluate a lower bound on the probability of a differential. This allows a forgery attack on the full LAC. This work

Cryptanalysis of an Image Encryption Scheme Based on a Compound Chaotic Sequence [PDF]
, 2007 Recently, an image encryption scheme based on a compound chaotic sequence was proposed. In this paper, the security of the scheme is studied and the following problems are found: (1) a differential chosen-plaintext attack can break the scheme with only ...
