<p>The invention concerns a method of making secure computation of an exponentiation of the type y=xr, where x is an element of a set having a multiplicative notation and r is a predetermined number, at least a bit or a figure r¿i? of said number r being processed at each iteration, and index i on the number r being provided, which consists at the end of each iteration, in incrementing or decrementing the index i in accordance with the value of the bit or figure indexed ri and rewriting at zero value the bit or figure indexed ri.</p> |
