WebAES has two steps that work together to thwart a known-plaintext attack. The actual round key and sbox steps simplified for explanation purposes would be something like for key k, ciphertext z = sbox (a * k) where the sbox is a simple substitution through a lookup table. Every byte is replaced with the corresponding byte from the table. thep a572WebDec 31, 2015 · The 10 rounds for AES-128 seem to be about the lower level of what is (approximately) 128-bit-secure, and 10 rounds for a AES-256-like-cipher would have way below 256 bits of security.
