I have two questions regarding the Block Cipher Modes: First: Which one of the modes is considered the best? I know CBC has a problem of IV since the next block of the plain text is XORed with the ...
Generate a 256-bit random nonce. XOR it with a 256-bit reusable symmetric key. This is x. We represent numbers in simple binary instead of a counting function. ...
The initial counter value can actually be thought of as a sort of IV, which I assume is safe to transmit with the ciphertext, but I really want to be sure that this is indeed safe.
