English term
a block cipher round module
English to French
Tech/Engineering
Patents
(in a patent) a whitebox descrambler
wherein a first block cipher round module uses a part of a predefined bit length of the ciphertext (C) as the input ciphertext data and wherein subsequent block cipher round use an output data of a previous block cipher round module as the input ciphertext data.
Each iteration is called a round, and the repeated function is called a round function. Typical block ciphers have 4 to 32 rounds.
Each block of ciphertext C is processed over 'n' rounds into the plaintext message 'M'. Each round 'r' receives its own round key 'RKr' as input, which is calculated from the original key 'K' in a key schedule module 501. In whitebox cryptography, each block cipher round module 4011,4012 is typically implemented using a sequence of table lookup operations hiding the value of the key 'K' and the roundkeys 'RKr' .
A block cipher round module 4011,4012 as shown in Fig.3 is shown in more detail in Fig.4. The block cipher round
function 401 contains two modules that operate in sequence...

un module de chiffrement/cryptage itératif par blocs
round = tour,
but "itératif" here since each iteration is called a round

"Chiffrement", if a choice needs to be made.
I first considered using "à tours" like Gilou but I find the rendering to be wordy given the fact that "par blocs" is already used. Maybe it's just me.

Merci. Le lien ne fonctionne pas mais je l'ai retrouvé. Le placement de "itératif" en fin de phrase, après "blocs", est moins utilisé il semble. Certainement une question de style.

This is such a rude thing to say. To me, frequency of use is a valid measure of consistency and complexity. It makes tons of sense in this field.

Discussion
but in a such highly technical field as is cryptography it's an utterly meaningless criteria. If you don't have a real understanding of underlying concepts, no "frequency of use" as criteria is going to ever help you
getting it right (except by pure accident)
