Abstract: A method includes protecting a boot sequence of a processing device by incrementing a counting value generated by a monotonic counter, then a first time period after the beginning of the boot sequence, comparing, by the protection circuit, the counting value with a first reference value, and, if the counting value is smaller than the first reference value, changing, by the protection circuit, the counting value to the first reference value.
