| 摘 要： | Zodiac算法是由一批韩国专家设计的一个分组密码算法。该文首次研究了Zodiac算法抵抗中间相遇攻击的能力。找到了Zodiac算法新的9轮区分器和10轮区分器，基于这两个区分器分别对15轮和完整16轮Zodiac算法进行了中间相遇攻击。结果表明完整16轮Zodiac-128/192/256是不抗中间相遇攻击的。

| Abstract: | Zodiac is a block cipher designed by a group of Korean experts.This paper studies the security of Zodiac against the meet-in-the-middle attack for the first time.Some new 9-round and 10-round distinguishers of Zodiac are found,and based on which some meet-in-the-middle attacks are made on 15-round and the full 16-round Zodiac.The results show that the full Zodiac-128/192/256 are not immune to the meet-in-the-middle attack. |
