    Abstract: A computing device comprises a network element configured for receiving messages sent over a network from a control facility, a reduced instruction set computer processing circuitry comprising a central processing unit (CPU) and a secure hardware-implemented module adapted to verify that a signed PKI message is encoded in the received messages at a plurality of sequential intervals and to either switch the CPU from an operational state to a safe state, or prevent switching of the CPU from the safe state to the operational state, when a receipt of a signed PKI message is not verified in one of the sequential intervals. In the operational state, the CPU accesses a memory address space in the processing circuitry for executing software-based commands. In the safe state the CPU is prevented from executing the software-based commands while access to the memory address space is retained.
