我们改进了Rijndael的最佳攻击，将复杂度从272降低到244，减少到6轮。我们还介绍了第一个已知的攻击7和8轮Rijndael。对8轮Rijndael的攻击适用于192位和256位密钥。最后，我们讨论了Rijndael的密钥调度，并描述了一个相关密钥攻击，可以打破9轮Rijndael与256位的密钥。
We improve the best attack on Rijndael reduced to 6 rounds from complexity 272 to 244. We also present the first known attacks on 7- and 8-round Rijndael. The attacks on 8-round Rijndael work for 192- bit and 256-bit keys. Finally, we discuss the key schedule of Rijndael and describe a related-key attack that can break 9-round Rijndael with 256-bit keys.
