 Okay, so thank you, good evening. So we are speaking about attempt analysis and how we help ASK integrate. So what is block cipher, this is the most commonly used, symmetric primitive. Which is turned to ciphertext using the key, most block ciphers are interactive, so a component of similar,RISM� forown. ואז אם ש alguém רוצה להקל ■ ■ ■ סקיורטי גרוע only linearly with the number of rounds due to differential linear analysis. Okay, so what is a good block cipher? We know the AES should be really the good block cipher, all of us believe that this is secure. So is AES a good block cipher? We're going to conclude the definition. So let's look at numbers of rounds and the best known attacks on these numbers. So the security level in the piece of, the AES has 10 rounds, 4 rounds has 10 bits of security, 5 rounds 32, 6 rounds 42, 7 rounds, already 99. You can see the euro complication of the attacks, it means that AES has started for 20 years, attacks appear to be quite rare. Okay, so does the security go exponentially with the number of rounds? No, we can see in the graph, no. So I'm sorry, Vincent, according to this definition, this is not a good block cipher. But we will make it great again, don't worry. So our new result represents here a cryptanalytic attack on 500 AES. So if we look at previous attacks on 500 AES, we say that the number is 2 to the 32, but actually there are full attacks with different techniques in different years, but all of them reached only the complexity of 2 to the 32, and this record was not broken the last 20 years. So our new result makes it 2 to the 22, so that is a thousand times speed up. So this is a new result to be presented at this crypto conference using some new technique of Grassy and some other techniques. Okay, so this is our attack. So why does it make AES great again? So let's look now at the updated security level of Redustal AES with this 22 and 5 rounds. So does the security go exponentially with a number of rounds? We see the graph, yes. So now we made AES. We have time for questions.
