Tamper-resistant smart factory

A retrofit access restriction kit configured to interface with an existing task-performing component and to permit the task-performing component to perform one or more tasks only when a verified task instruction is received by the kit, the kit comprising:

• a true random number generator (TRNG) configured to generate true random keys that are based on quantum-level physical properties;
• a hub computer configured to provide true random keys that are generated by the TRNG;
• a component computer that is configured to interface with the task-performing component, wherein the component computer is configured to receive true random keys provided by the hub computer and to store the true random keys received to a memory and is further configured to receive and verify task instructions and to then provide verified task instructions to the task-performing component;
• and
• a controller that is configured to provide a task request to the component computer, wherein each task request includes a task instruction paired with a key,
• wherein, in response to receiving the task request from the controller, the component computer verifies the task instruction by comparing and ensuring that the true random key stored to the memory matches the key received from the controller with the task request and then provides the verified task to the task-performing component.

A method for securing a task-performing component comprising the steps of:

• providing an access restriction system having:
• a true random number generator (TRNG) that is configured to generate true random keys that are based on quantum-level physical properties;
• a hub computer that is configured to provide true random keys that are generated by the TRNG;
• an access-restricted component configured to execute one or more tasks in response to receiving a verified task instruction;
• a component computer that is configured to receive true random keys provided by the hub computer and to store the true random keys received to a memory, and is configured to receive and verify task instructions and to then provide verified task instructions to the access restricted component;
• a controller that is configured to provide a task request to the component computer, wherein each task request includes a task instruction paired with a key,
• generating a true random key with the TRNG;
• providing the true random key to the component computer using the hub computer;
• storing the true random key to the memory of the component computer;
• sending a task request from the controller to the component computer;
• verifying the task instruction of the task request by ensuring that the true random key stored to the memory matches the key received from the controller with the task request;
• providing the verified task to the access-restricted component with the component computer;
• and
• carrying out one or more tasks specified by the task instruction with the access-restricted component.
