Goal (sport) Goals can be disallowed if there is an infraction by the offensive team. The goal in lacrosse is tall and wide and a net is used to prevent the ball from reentering the field of play. Lacrosse goals are not positioned on the end boundary line, play often occurs behind the goal. In netball, a goal is scored when the ball is shot through a goal ring on a pole. In polo, a goal is scored if the ball passes completely between the goal posts, regardless of how far off the ground the ball is. The ball must be between
3-subset meet-in-the-middle attack carry out the MITM attack, the 3 subsets are bruteforced individually, according to the procedure below: Each key-candidate found in the key-reducing phase, is now tested with another plain-/ciphertext pair. This is done simply by seeing if the encryption of the plaintext, P, yields the known ciphertext, C. Usually only a few other pairs are needed here, which makes the 3-subset MITM attack, have a very little data complexity. The following example is based on the attack done by Rechberger and Bogdanov on the KTANTAN cipher-family. The naming-conventions used in their paper is also used for this example. The attack
