ABSTRACT:
The invention relates to a cryptographic method secured against a covert channel attack. According to the invention, in order to carry out a selected block of instructions as a function of an input variable amongst N predefined instruction blocks, a common block is carried out on the predefined N instruction blocks, a predefined number of times, the predefined number being associated with the selected instruction block.
