Abstract: The present invention relates to a method to provide a dynamic change of security configurations in an integrated circuit product adapted to execute at least a given critical process and susceptible to be attacked. The method comprises the steps of tracking successive executions of the given critical process, and after a given number of such executions, triggering a change of the security configuration.

Abstract: The invention relates to a random clock generator comprising an input receiving a master clock signal MCIk, and a clock signal reduction circuit (101) receiving the master clock signal MCIk and a whole number N and supplying an output signal corresponding to a train of N pulses every M clock pulse, M being a whole number higher than 1 and N being a whole number higher than 1 and lower than or equal to M. A number generator (102) and (103) supplies a new number (N) to the clock signal reduction circuit every P pulse of a master clock signal, N and/or P being produced randomly.

Abstract: The present invention relates to a secure platform implementing dynamic countermeasures in relation with the execution of a code, said secure platform having at least a security sensor, a countermeasure controller and countermeasure means. According to the invention, said countermeasure controller includes at least one security sensor flag able to take at least two sensor flag values depending on the output of the security sensor, a table storing N possible security configuration for the countermeasures, a random generator to generate a random configuration value, a decision function using the sensor flag value and the random configuration value to determine a security configuration in the table to be executed by countermeasure means.
