Abstract: A hardware security module (HSM) transitions a first signal from a first state to a second state and transitions a second signal from a first state to a second state when a request to change boot code is received. In response to receipt of a boot request, the HSM, when the first signal is in the first state and the second signal is in the first state: does not execute the hash function; and maintains the second signal in the first state. An actuator control module, in response to the receipt of the boot request: executes the boot code when the second signal is in the first state; and does not execute the boot code when the second signal is in the second state.
