In cryptography, NUSH is a block cipher invented by Anatoly Lebedev and Alexey Volchkov for the Russian company LAN Crypto. It was submitted to the NESSIE project, but was not selected.
NUSH exists in several different variants, using keys of 128, 192, or 256 bits, and a block size of 64, 128, or 256 bits. The number of rounds is 9, 17, or 33, depending on the block size. The algorithm uses key whitening, but no S-boxes; the only operations it uses are AND, OR, XOR, modular addition, and bit rotation.
It has been shown that linear cryptanalysis can break NUSH with less effort than a brute force attack.
Let's go, children of the fatherland,
Our day of glory has arrived.
Against us Tyranny
Has raised its bloody flag.
Allons enfants de la Patrie,
Le jour de gloire est arrive!
Contre nous de la tyrannie
L'etendard sanglant est leve!
Do you hear it in the fields
And on the streets,
The howling of the savage force?
They come right into our house
To cut the throat of our mother -
France.
Amour sacre de la Patrie,
Conduis, soutiens nos bras vengeurs!
Liberte, Liberte cherie,
Combats avec tes defenseurs!
Traitors, criminals, delinquents, slaves,
What do they want - these foreign hordes?
Why do they carry chains,
Molotovs, iron stakes
And all their weapons?
Is it really us they dare to touch?
Do they want to be US so much?
Listen to the sound on the streets
And in the ghetto, listen!
Listen to these mercenaries,
Stone-throwers, pyromaniacs, listen!
Un-named barbarians, traitors,
The rabble, listen!
Listen to the roaring
Of this fearsome force, listen!
Under their flag of Victory and Freedom!
It's never too late
