摘要
This 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).
