Thanks for this wonderful lecture, I'm always happy that your lectures are in English which allows me as an international student to understand this subject

What about a known ciphertext attack when attacker have a couple of cipher and decrypted cipher = plaintext ?

Then why did they choose two-fish over Raj-13 for AES standard?

I have college assignment, Differential cryptanalysis attack on Feal-4 algorithm , we have choose plain text and cipher text. I have done four rounds. and got 6 subkeys. , when i use the six sub keys to encrypt and decrypt , verification working fine , but my college professor. say like this . below. Only one value is given for each key - most are out by a few bits, but one is correct. Code seems to be largely based on Amazing Kings, without any real understanding of how the attack works what's your opinion on it.

don't understand at all. talk too fast as though the presenter is trying to beat the clock. i watch and watch many times trying to understand, especially the chosen plaintext and chosen ciphertext. still don't understand the explanation. actually it is not only this presenter. i find that none of those videos I've watched so far actually explain these concepts clearly. even college textbooks written by super well-known authors can't explain the concepts clearly. no wonder students are never able to understand, because the textbooks are basically useless and the teachers based on the textbooks can't explain, because the textbooks the teachers use can explain the concepts. it's a joke seriously. i find that these attacks make no sense. perhaps just trying to invent these concepts to confuse people.
