Abstract: Linear cryptanalysis, a Known-Plaintext Attack, for symmetric block cipher works by constructing linear approximations of the non-linear components of the cipher. The only component which introduces non-linearity in the symmetric block cipher is an S-box. Using classical computing algorithms, the best known solution to find a linear approximation.
Keywords: Linear Cryptanalysis, Linear Approximation.
Scope of the Article: Pervasive Computing.
