Abstract:
A method of checking the authenticity of the content of a non-volatile memory of an electronic device including a microcontroller and an embedded secure element includes starting the microcontroller with instructions stored in a first non-reprogrammable memory area associated with the microcontroller, starting the secure element, executing, with the secure element, a signature verification on the content of a second reprogrammable non-volatile memory area associated with the microcontroller, and interrupting the microcontroller power supply if the signature is not verified.
