摘要： A method of cryptographic processing of data (X), in particular a method protected against fault injection attacks, and an associated device. The processing includes at least one transformation (100, 1001-1006) of an input data item (s) into a result data item (s′). In this case the method includes a step (E204) of verifying the transformation including the following steps: obtaining (E206) a first data item (DV(s′)) that is compressed by applying a compression operation (110, MDV, ADV) to the result data item (s′); obtaining (E208) a second compressed data item (DV(s)) that is compressed by applying the compression operation (110, MDV, ADV) to the input data item (s); determining (E210) a verification data item (DV(s)′) by applying the transformation (100, 1001-1006) to the second compressed data item (DV(s)) and; comparing (E212) the verification data item and the first compressed data item.
摘要翻译：该方法包括进行变换，例如。将输入数据项的乘法逆变换（MIT）转换成结果数据项。获得通过对结果数据项应用压缩操作来压缩的数据项。获得通过将操作应用于输入数据项而压缩的另一数据项。通过将变换应用于后一个压缩数据项来确定验证数据项。将验证数据项和前一压缩数据项进行比较，以验证输入数据项到结果数据项的变换。还包括用于数据的密码处理的设备的独立权利要求。
