So yes they are. But since you normally cannot do that without having the secret key it's most of the time not practically relevant. – eckes Jul 12, 2024 at 10:28

WebHowever, a birthday attack (e.g. both x and y can be selected arbitrarily, but H ( x) = H ( y) is of course still required) is supposed to be much faster, and take only 2 n / 2 tries to find a collision. WebThe birthday attack is a statistical phenomenon relevant to information security that makes the brute forcing of one-way hashes easier. It’s based off of the birthday paradox, which states that in order for there to be a 50% chance that someone in a given room shares your birthday, you need 253 people in the room.
