The Independence of Linear Approximations in Symmetric Cryptanalysis

open access: yes, 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 ...

Resistance of Balanced S-boxes to Linear and Differential Cryptanalysis

open access: yes, 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).
