Modeling and application of AND gates’s correlation in linear cryptanalysis

Cybersecurity
With the increasingly widespread application scenarios of the Internet of Things, the demand for lightweight ciphers continues to grow. For some lightweight ciphers whose only nonlinear component is the AND gate, their resistance to linear cryptanalysis ...

Differential-Linear Cryptanalysis of Reduced Round ChaCha

IACR Transactions on Symmetric Cryptology
ChaCha is a well-known stream cipher that has been used in many network protocols and software. In this paper, we study the security of reduced round ChaCha. First, by considering the differential-linear hull effect, we improve the correlation of a four-

The Independence of Linear Approximations in Symmetric Cryptanalysis

, 2008
— A theoretical framework for the use of multiple linear approximations in the linear cryptanalysis of block ciphers is given. The covariance of two mask counts is derived, and it is shown that under appropriate conditions the mask counts in linear ...

New Linear Trails and Linear Hulls of CHAM

IEEE Access
CHAM is a family of lightweight block ciphers with block sizes of 64 bits and 128 bits. CHAM performs very well in lightweight environments and is known to be one of the block ciphers that can be implemented with the smallest hardware area. In this paper,

Resistance of Balanced S-boxes to Linear and Differential Cryptanalysis

, 2007
: In this letter, we study the marginal density of the XOR distribution table, and the linear approximation table entries of regular substitution boxes (s-boxes).

A Unified Markov Approach to Differential and Linear Cryptanalysis

, 1994
Differential and linear cryptanalysis are two attacks on product ciphers that use approximations of the round function F to derive information about the secret key.

Feistel Schemes and Bi-linear Cryptanalysis [PDF]

, 2004
In this paper we introduce the method of bi-linear cryptanalysis (BLC), designed specifically to attack Feistel ciphers. It allows to construct periodic biased characteristics that combine for an arbitrary number of rounds. In particular, we present a practical attack on DES based on a 1-round invariant, the fastest known based on such invariant, and ...

Linear Key-schedule’s Properties of the Smallpresent Block Cipher

Безопасность информационных технологий, 2013
SmallPresent block cipher was presented to investigate attacks on the PRESENT block cipher in details. In the paper the resistance to linear cryptanalysis of this cipher with arbitrary linear key-schedule is under consideration.

Theoretical Linear Cryptanalysis of the 5G Standard Candidate SNOW 5G

IACR Transactions on Symmetric Cryptology
In this paper, we perform linear cryptanalysis of the stream cipher SNOW 5G, which is recommended by the international standardization group (SAGE) as one standard algorithm for 5G confidentiality and integrity protection over the wireless channel. SNOW
