在本文中，我们展示了Demirci-Selcuk-Ture攻击是如何显著提高性能的，这是目前针对IDEA分组密码的最深穿透攻击。所提出的改进减少了攻击的明文、内存、预计算时间和键搜索时间的复杂性。这些改进还使对IDEA简化版本的攻击的实际实现成为可能，从而使DST攻击的首次实验验证成为可能。
In this paper, we show how the Demirci-Selcuk-Ture attack, which is currently the deepest penetrating attack on the IDEA block cipher, can be improved significantly in performance. The improvements presented reduce the attack’s plaintext, memory, precomputation time, and key search time complexities. These improvements also make a practical implementation of the attack on reduced versions of IDEA possible, enabling the first experimental verifications of the DST attack.
