I'm working and reading about bit-flipping attack and how to set it up. I just got a question, which I am not sure, how I should answer.
Question: 'Why is this easy with a stream cipher but not possible with a block cipher in, e.g., CBC mode?'.
Stream cipher is a symmetric-key-encryption algorithm, which encrypts a stream of bits, where block cipher is an algorithm that allowing us to encrypt blocks of a fixed length. But I can't really find an answer why it's not possible with block cipher and possible with stream chipher.
From what I understand and can read from this thread, that it is possible, but this thread may not be relevant for me.
Anyone, that got an explanation on this?
