离散旋转算子DRT及其在某些流密码中的应用
Disperse rotation operator DRT and use in some stream ciphers
摘要：
旋转运算符经常用于几种流密码，包括HC-128、Rabbit和Salsa 20，它们是eSTREAM的最终候选者。这是因为旋转操作符（ROT）很简单，但具有很好的可扩展性。本文提出了一种离散旋转算子（DRT），它具有与ROT相同的结构，但具有更好的可伸缩性。此外，使用DRT代替ROT表明，所有三种流密码的输出流的质量都得到了显着改善。然而，在HC-128流密码中使用DRT而不是ROT阻止了基于LSB的差分攻击的扩展。
英文摘要：
The rotation operator is frequently used in several stream ciphers, including HC-128, Rabbit, and Salsa20, the final candidates for eSTREAM. This is because the rotation operator (ROT) is simple but has very good dispersibility. In this paper, we propose a disperse rotation operator (DRT), which has the same structure as ROT but has better dispersibility. In addition, the use of DRT instead of ROT has shown that the quality of the output stream of all three stream ciphers was significantly improved. However, the use of DRT instead of ROT in the HC-128 stream cipher prevents the expansion of differential attacks based on LSB.
