在本文中，我们提出了一个全新的MISTY1攻击。 攻击使用Todo的6轮积分特性[11]在加密方向（如Todo所使用的）和解密方向。 从特征导出的攻击方程为错误的关键猜测提供了一个过滤。 我们的攻击具有269.5加密的时间复杂度，通过使用部分和，二维中间和其他技术有效地利用过滤。 与Todo的时间复杂度为2^107.3加密的攻击相比，这减少了2倍38。(In this article, we have proposed a new MISTY1 attack. The attack uses the Todo's 6 - wheel integral feature [11] in the encrypted direction (as used by Todo) and the decryption direction. The attack equation derived from the feature provides a filter for the critical guess of the error. Our attacks have 269.5 encrypted time complexity, which effectively use filtering by using parts and, two-dimensional intermediate and other techniques. This reduced by 2 times 38 compared to the time complexity of Todo for 2^107.3 encrypted attacks.)
