An Improved Fast Correlation Attack on Stream Ciphers [PDF]
, 2009 At Crypto'2000, Johansson and Jonsson proposed a fast correlation attack on stream ciphers based on the Goldreich-Rubinfeld-Sudan algorithm. In this paper we show that a combination of their approach with techniques for substituting keystream and evaluating parity-checks gives us the most efficient fast correlation attack known so far.

Two Attacks Against the HBB Stream Cipher [PDF]
, 2005 Hiji-Bij-Bij (HBB) is a new stream cipher proposed by Sarkar at Indocrypt’03. In this algorithm, classical LFSRs are replaced by cellular automata (CA). This idea of using CAs in such constructions was initially proposed by Sarkar at Crypto’02, in order to instantiate its new Filter-Combiner model.

Efficient Cipher-Only Attack of a Stream Cipher in RDHEI Based on Pixel Smoothness Estimation
EasyChair Preprints, 2019 Reversible data hiding in encrypted images (RDHEI) has recently emerged as an effective approach to protect the confidentiality of image content through encryption while assisting in the management of encrypted images by lossless hiding some additional ...

PudgyTurtle Mode Resists Bit-Flipping Attacks
Cryptography, 2023 Cryptosystems employing a synchronous binary-additive stream cipher are susceptible to a generic attack called ’bit-flipping’, in which the ciphertext is modified to decrypt into a fraudulent message.

A Fault Attack on the Family of Enocoro Stream Ciphers
Cryptography, 2021 A differential fault attack framework for the Enocoro family of stream ciphers is presented. We only require that the attacker can reset the internal state and inject a random byte-fault, in a random register, during a known time period. For a single fault injection, we develop a differential clocking algorithm that computes a set of linear equations ...

IACR Transactions on Symmetric Cryptology, 2022 Draco is a lightweight stream cipher designed by Hamann et al. in IACR ToSC 2022. It has a Grain-like structure with two state registers of size 95 and 33 bits. In addition, the cipher uses a 128-bit secret key and a 96-bit IV.

Slide attacks on the Sfinks stream cipher [PDF]
2012 6th International Conference on Signal Processing and Communication Systems, 2012 Sfinks is a shift register based stream cipher designed for hardware implementation and submitted to the eSTREAM project. In this paper, we analyse the initialisation process of Sfinks. We demonstrate a slid property of the loaded state of the Sfinks cipher, where multiple key-IV pairs may produce phase shifted keystream sequences.

Using Evolving Algorithms to Cryptanalysis Nonlinear Cryptosystems
مجلة بغداد للعلوم, 2020 In this paper, new method have been investigated using evolving algorithms (EA's) to cryptanalysis one of the nonlinear stream cipher cryptosystems which depends on the Linear Feedback Shift Register (LFSR) unit by using cipher text-only attack.

Findings Annihilator(s) via Fault Injection Attack (FIA) on Boolean Function of Grain v0 [PDF]
ITM Web of Conferences, 2019 In developing stream cipher algorithms, Boolean function is one of vital elements. Attacks on LFSR-based stream cipher is the challenge for the cryptanalyst to get low-degree annihilator(s).
