在本文中，我们提出了一个密码分析技术，基于不可能的差异。我们用它来表明，恢复密钥的Skipjack减少到31轮，可以比穷举搜索更快地执行。我们还描述了Yoyo游戏（一种可以用来对付减少回合的Skipjack的工具），以及Skipjack的其他属性。
In this paper we present a cryptanalytic technique, based on impossible differentials. We use it to show that recovering keys of Skipjack reduced from 32 to 31 rounds can be performed faster than exhaustive search. We also describe the Yoyo game (a tool that can be used against reduced-round Skipjack), and other properties of Skipjack.
