Abstract:
A method is to de-correlate electric signals emitted by an IC Card during computations as well as sensitive data involved in such computations. The method includes executing functions introducing respective electric signals which do not involve the sensitive data. Each of the functions is triggered by a timer having a value which is different at each step of executing the functions.
