Abstract
A system for securing an electronic circuit including: plural regions, activity of each of which may be controlled; plural sensors integrated into the electronic circuit, each sensor being sensitive to variations in manufacturing process and to provide a measurement representative of a local activity of the electronic circuit; a processing unit including an integrity verification module configured to: determine, based on the measurements provided by the sensors, and for each of the regions, a partition of the sensors between sensors affected and sensors not affected by an activation of the region; compare each of the partitions with a model partition to detect possible presence of a hardware Trojan horse liable to infect the electronic circuit. The system can carry out an authentication of the electronic circuit by its intrinsic physical characteristics by response to a challenge or by generation of a key.
