Abstract:
The invention relates to a method for protecting a sensitive operation by checking the integrity of at least a subset of the data manipulated by the sensitive operation. Data to be checked are divided into blocks, an intermediate integrity check value being computed for each block, the intermediate integrity check values being computed in random order. The invention also relates to a cryptographic device wherein at least one sensitive operation of the cryptographic device is protected by a method according to the invention.
