There are many kinds of attacks that can be mounted on
block ciphers: differential attacks, impossible differential attacks, truncated
differential attacks, boomerang attacks. We consider generic di...

A usual way to construct block ciphers is to apply several
rounds of a given structure. Many kinds of attacks are mounted against
block ciphers. Among them, differential and linear attacks are widel...
