置换网络(SPN)是分组密码的一种主要结构形式。针对SPN结构提出了一种新的实用的差异化故障攻击技术。作为SPN密码的一个实例，AES-256可以被4个错误密文恢复。与以前的技术相比，我们的工作可以用S所证明的所有密钥来恢复一个n个SPN密码的所有子密钥。因此，我们对AES的攻击方法不仅提高了错误注入的效率，而且减少了错误密文的数量。这为分组密码的故障分析提供了一种新的方法。
The Substitution-Permutation Network (SPN) is a main type of structure in block ciphers. This paper proposes a new and practical differential fault attack technique on SPN structure. As an instance of SPN cipher , AES-256 can be recovered by 4 faulty ciphertexts. Compared with the previous techniques, our work can recover all subkeys of a n SPN cipher with all key s izes. Therefore , our attacking method on AES not only improves the efficiency of fault injection, but also decreases the number of faulty ciphertexts. It provides a new approach for fault analysis on block ciphers.
