Nov 3 '19 at 15:59 comment added Ella Rose @ÖmerEnesÖzmen Your questions are easily answered by simply familiarizing yourself with the design of AES. It's not complicated, there are really only a handful of steps, and one of those steps provides an answer to your question
Nov 3 '19 at 15:29 comment added Ömer Enes Özmen @Ella Rose no..but they have to be key independent right? Cuz if they're fixed then anybody can reverse the ciphertext right?
Nov 3 '19 at 15:23 comment added Ella Rose Have you read the definition of AES, specifically what the steps involved in it are?
Nov 3 '19 at 15:09 comment added Ömer Enes Özmen I think I was mistaking with blowfish then...but if the substitution-permutation boxes are fixed, then anybody can reverse the encryption process right? Now I know if this was true then it wasn't the standard for the government, but still, if they're fixed, how?
Nov 2 '19 at 22:51 comment added Ella Rose Where did you read that the keys determine the S and P boxes for AES? Considering that AES does not have a P-box as such, the source is suspect.
Nov 2 '19 at 20:54 comment added Dan Commenting not answering b/c I'm not sure if I recall correctly. My recollection is that with AES (per your question), the substitution and permutation operations are not key-dependent. However, with some ciphers (e.g. Blowfish), the operations do depend on the key.
