Decimation Attack of Stream Ciphers [PDF]
, 2000 This paper presents a new attack called Decimation Attack of most stream ciphers. It exploits the property that multiple clocking (or equivalently d-th decimation) of a LFSR can simulate the behavior of many other LFSRs of possible shorter length. It yields then significant improvements of all the previous known correlation and fast correlation attacks.

MV3: A new word based stream cipher using rapid mixing and revolving buffers [PDF]
, 2006 MV3 is a new word based stream cipher for encrypting long streams of data. A direct adaptation of a byte based cipher such as RC4 into a 32- or 64-bit word version will obviously need vast amounts of memory. This scaling issue necessitates a look for new

On the Security of Y-00 under Fast Correlation and Other Attacks on the Key [PDF]
, 2006 The potential weakness of the Y-00 direct encryption protocol when the encryption box ENC in Y-00 is not chosen properly is demonstrated in a fast correlation attack by S. Donnet et al in Phys. Lett. A 35, 6 (2006) 406-410.

A Novel Binary Hybrid PSO-EO Algorithm for Cryptanalysis of Internal State of RC4 Cipher
Sensors, 2022 Cryptography protects privacy and confidentiality. So, it is necessary to guarantee that the ciphers used are secure and cryptanalysis-resistant. In this paper, a new state recovery attack against the RC4 stream cipher is revealed.

Differential fault location identification by machine learning
CAAI Transactions on Intelligence Technology, 2021 As the fault‐based attacks are becoming a more pertinent threat in today's era of edge computing/internet‐of‐things, there is a need to streamline the existing tools for better accuracy and ease of use, so that we can gauge the attacker's power and a ...

Improved Fast Correlation Attacks on the Sosemanuk Stream Cipher
IACR Transactions on Symmetric Cryptology, 2023 In this paper, we present a new algorithm for fast correlation attacks on stream ciphers with improved cryptanalysis results on the Sosemanuk stream cipher, one of the 7 finalists in the eSTREAM project in 2008. The new algorithm exploits the direct sum

Improving OBDD attacks against stream ciphers
Математические вопросы криптографии, 2020 При атаках на поточные шифры диаграммами последовательных бинарных решений (ДПБР) секретное начальное состояние вычисляется с помощью набора из $\mathcal{O}(n)$ ДПБР максимальной ширины $\mathcal{O}(2^{\frac{1-\alpha}{1+\alpha}n})$, где $n$ - длина внутреннего состояния, а $\alpha\in (0,1)$ - степень сжатия шифра.
