我有一个项目，我必须为我的 Arduino Uno R3 实现各种安全协议(protocol)，例如 Present、Misty、Prince 等。目前我正在尝试实现 Midori128。我设法让 Midori64 正常工作，但对于 Midori128，加密不正确，而解密工作正常。
这是目前的代码，请记住我从 GitHub 中提取了此代码，然后对其进行更改以使其尽可能高效地在 Arduino 上工作；但就像我说的，加密不正确，我不知道为什么。

我看了很多遍原论文，对这个方法也很了解，但我无法确定它没有输出正确密文的确切原因，即c055cbb95996d14902b60574d5e728d6。任何帮助或提示将不胜感激。谢谢你。
后期编辑:
我设法找到了 Midori128 中使用的 4 个 sbox，但是，我仍然不知道如何将它们准确地合并到我的代码中，如果有人有任何想法，我将不胜感激。
