WebThat means it takes about 2 n − 1 tries on average to find a colliding message y for a given message x so that H ( y) = H ( x) while y ≠ x. However, 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.
