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.展开▼
