Abstract:
A method for protecting an integrated circuit. According to the method, the start-up of all, or part, of the circuit is determined in the presence of a key which is recorded in a non-volatile manner in the circuit, following the production thereof, and depends on at least one first parameter which is present in a non-volatile manner in the circuit after the production thereof.
