Linear cryptanalysis is a known plaintext attack in which the attacker studies probabilistic linear relations (called linear approximations) between parity bits of the plaintext, the ciphertext, and the secret key. ... Using auxiliary techniques he can usually extend the attack to find more bits of the secret key.

What is cryptanalysis explain in brief differential and linear cryptanalysis?

The two main classes of statistical cryptanalysis are the linear and differential attacks. ... The idea of differential-linear cryptanalysis is to apply first a truncated differential attack and then a linear attack on different parts of the cipher and then combine them to a single distinguisher over the cipher.

What is the difference between linear and differential cryptanalysis?

What is the difference between linear and differential cryptanalysis? Differential cryptanalysis works by comparing the input plaintext to the output ciphertext, while linear cryptanalysis runs plaintext through a simplified version of the cipher to attempt to deduce the key.
