|---|---|
| Abstract | The invention relates to a digital electronic component which is protected against electrical- and/or electromagnetic-type analyses. The inventive component comprises: a synchronous element (10) which is controlled by a clock (H); means (11, 12) of generating said clock (H), the frequency of which varies randomly between a minimum value and a maximum value for at least a given period of time; and means (13) of controlling the random nature of the frequency change of said clock (H). (FR) La présente invention décrit un composant électronique numérique protégé contre des analyses de type électrique et/ou électromagnétique comprenant un élément synchrone (10) piloté par une horloge (H), des moyens (11, 12) de génération de cette horloge (H) dont la fréquence varie de manière aléatoire entre une valeur minimum et une valeur maximum pendant au moins une période de temps donnée, et des moyens (13) de contrôle du caractère aléatoire du changement de fréquence de cette horloge(H). |
