Abstract
There is disclosed a system for monitoring the security of a target system () with a circuit (), the target system () comprising at least one processor () and wherein: the circuit () comprises a finite-state machine () configured to receive data from one or more sensors () distributed in the target system (), at least one sensor () being located on the processor () of the target system (); the finite-state machine () is configured to determine a state output in response to data received from sensors (); the system monitoring the security based on said state output. Developments describe the use of a self-alarm mechanism comprising an encoder to encode states with redundancy, the application of an error correction code, comparisons with predefined valid encoded states, the triggering of an alarm to the processor, the determination of actions and/or retroactions on sensors and/or diagnostics and countermeasures.
