Cryptanalysis of the stream cipher BEAN [PDF]
Proceedings of the 4th international conference on Security of information and networks, 2011 BEAN is a recent stream cipher proposal that uses Feedback with Carry Shift Registers (FCSRs) and an output function. There is a sound motivation behind the use of FCSRs in BEAN as they provide several cryptographically interesting properties. In this paper, we show that the output function is not optimal.

Using Hadamard transform for cryptanalysis of pseudo-random generators in stream ciphers [PDF]
EAI Endorsed Transactions on Energy Web, 2020 In this work we discuss results obtained from an application of the Hadamard transform to cryptanalysis, andin particular, we determine the probability to decipher different pseudo-random number generators used ascomponents of stream ciphers.

Automatic Search of Cubes for Attacking Stream Ciphers
IACR Transactions on Symmetric Cryptology, 2021 Cube attack was proposed by Dinur and Shamir, and it has become an important tool for analyzing stream ciphers. As the problem that how to recover the superpolys accurately was resolved by Hao et al. in EUROCRYPT 2020, another important problem is how to

Linear Attacks on Stream Ciphers
, 2011 This paper is a survey of how linear attacks can be applied on stream ciphers. It gives an overview of the development of linear attacks and a short theoretical explanation on how a linear attack on a stream cipher is typically launched today.

Bias in the LEVIATHAN Stream Cipher [PDF]
, 2002 We show two methods of distinguishing the LEVIATHAN stream cipher from a random stream using 236 bytes of output and proportional effort; both arise from compression within the cipher. The first models the cipher as two random functions in sequence, and shows that the probability of a collision in 64-bit output blocks is doubled as a result; the second

Bit Independence Criterion Extended to Stream Ciphers
Applied Sciences, 2020 The bit independence criterion was proposed to evaluate the security of the S-boxes used in block ciphers. This paper proposes an algorithm that extends this criterion to evaluate the degree of independence between the bits of inputs and outputs of the ...

Resistance of SNOW-V against Fast Correlation Attacks
IACR Transactions on Symmetric Cryptology, 2021 SNOW-V is a new member in the SNOW family of stream ciphers, hoping to be competitive in the 5G mobile communication system. In this paper, we study the resistance of SNOW-V against bitwise fast correlation attacks by constructing bitwise linear ...

Fruit-80: A Secure Ultra-Lightweight Stream Cipher for Constrained Environments
Entropy, 2018 In Fast Software Encryption (FSE) 2015, while presenting a new idea (i.e., the design of stream ciphers with the small internal state by using a secret key, not only in the initialization but also in the keystream generation), Sprout was proposed. Sprout
