Abstract
A method for masking several identical functional processes manipulating digital data, including dividing the functional processes into steps at the end of each of which the process can be interrupted with the storage of at least one intermediary result, and successively executing the steps of at least two processes and selecting, at each step end, the process of the next step according to the result of a non-deterministic drawing of a number.
