On the contrary, in a security argument or Proof, you have to assume the attacker knows everything accept the key. | |
Mar 9, 2023 at 17:54 | comment | added | poncho | If you're truly paranoid, you'll pad out all messages to a constant length (and send encrypted messages at regular intervals, whether or not you have a message to send). In that case, we've already answered the question of "whether to use padding or not" | |

Feb 10, 2022 at 12:15 | comment | added | r s | Yes, it is just a way of keeping clear that we are using the basis concept of an additive stream cipher there (XORing the input bytes out with an iterative computation of what would be the keystream). | |
Feb 10, 2022 at 7:11 | comment | added | Mikero | BTW: The category of modes containing CTR, OFB, etc is usually called "stream cipher" modes, not "additive" modes. | |
