Abstract:
A protection mechanism for the execution of an encryption algorithm is disclosed. In the mechanism the encryption algorithm has its execution preceded by an update of a counter stored in a reprogrammable non-volatile memory. Storing the value of the counter into the memory corresponds with the execution of the algorithm.
