Abstract

The invention relates to a method for handling data (A, B) between two memory areas (W, R1, R2) of an electronic component comprising at least one working memory area (W) for carrying out operations on said component bringing into play at least one of said data. The inventive method is characterized in that it involves the use of the same memory areas for executing an operation whatever the operation to be executed is in such a manner that each operation has a hidden signal trace that is identical in terms of location leakage outside this component.
