Algebraic Description and Simultaneous Linear Approximations of Addition in Snow 2.0. [PDF]
, 2008 In this paper we analyse the algebraic properties over the field GF(2) of the addition modulo 2pn. We look at implicit quadratic equations describing this operation, and at probabilistic conditional linear equations.

BLOSTREAM: A HIGH SPEED STREAM CIPHER [PDF]
Journal of Engineering Science and Technology, 2017 Although stream ciphers are widely utilized to encrypt sensitive data at fast speeds, security concerns have led to a shift from stream to block ciphers, judging that the current technology in stream cipher is inferior to the technology of block ciphers.

Randomness of encryption keys generated by super H-antimagic total labeling
Indonesian Journal of Combinatorics, 2020 SuperH-antimagic total labeling (SHATL) can be utilized to generate encryption keys. The keys are then used to establish the improved block and stream ciphers.

Tabu Search Against Permutation Based Stream Ciphers [PDF]
International Journal of Electronics and Telecommunications, 2018 Encryption is one of the most effective methods of securing data confidentiality, whether stored on hard drives or transferred (e.g. by e-mail or phone call). In this paper a new state recovery attack with tabu search is introduced. Based on research and

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

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 ...

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
