On relationship between differential/linear clustering effects and the number of active S-boxes in block ciphers

Cybersecurity
Differential cryptanalysis and linear cryptanalysis are the two best-known cryptanalysis techniques for symmetric-key primitives. Ensuring resistance to these attacks is critical for the security of block ciphers.

Revisiting the shuffle of generalized Feistel structure

Cybersecurity
The Generalized Feistel Structure ( $$\texttt{GFS}$$ GFS ) is one of the most widely used frameworks in symmetric cipher design. In FES 2010, Suzaki and Minematsu strengthened the cryptanalysis security of $$\texttt{GFS}$$ GFS by searching for shuffles ...

Links Between Differential and Linear Cryptanalysis

, 1994
Linear cryptanalysis, introduced last year by Matsui, will most certainly open-up the way to new attack methods which may be made more efficient when compared or combined with differential cryptanalysis.

Ultrametric integral cryptanalysis [PDF]

A systematic method to analyze divisibility properties is proposed. In integral cryptanalysis, divisibility properties interpolate between bits that sum to zero (divisibility by two) and saturated bits (divisibility by $2^{n - 1}$ for $2^n$ inputs ...

State recovery attack on ACORN v3 in nonce-reuse setting

Tongxin xuebao, 2020
Based on differential-algebraic method and guess-and-determine technique,the state recovery attack of ACORN v3 was presented when one pair of key and Nonce was used to encrypt two messages.The time complexity of the attack was 2122.5c,where c was the ...
