Automated banking machine firmware flow control

An apparatus, comprising:

• a core module controller located within a safe, the safe containing a cassette that holds sheets for dispensing, the core module comprises a trusted platform module;
• a gate controller operable to control a gate for dispensing sheets from the cassette;
• and
• an unsecure bus communicatively coupling the core module controller with the gate controller;
• the core module controller comprises logic for exchange a digital certificate with the gate controller, the gate controller having access to at least one public key of one of a group consisting of the core module controller and the trusted platform module the core module controller comprises logic for receiving a random number from the gate controller;
• the core module controller comprises logic for employing the trusted platform module to generate a message signed with a private key of the trusted platform module, the message comprises the random number received from the gate controller, a random number generated by one of a group the core module controller and the trusted platform module, an identifier associated with the gate controller, and a key block encrypted by one of a group the core module controller and the trusted platform module, the key block comprises a distinguishing identifier associated with the one of a group the core module controller and the trusted platform module generating the key block and a session key;
• the core module controller comprises logic for sending the message to the gate controller
• the core module controller comprises logic for receiving from the gate controller a message signed by the private key associated with the public key included in the gate controller's verification certificate, the message comprises the random number received from the gate controller, the random number generated by the one of a group consisting of the core module controller and trusted platform module and the distinguishing identifier for the one a group consisting of the core module controller and trusted platform module;
• the core module controller comprises logic for employing the trusted platform module to verify a signature of the message received from the gate controller, the trusted platform module employing a public verification key included in a digital certificate for the gate controller;
• the core module controller comprises logic for verifying a random for the gate controller in the message signed by the private key received from the gate controller matches the random number previously received from the gate controller;
• the core module controller comprises logic for verifying a random number for one of a group consisting of the core module controller and the trusted platform module in the message signed by the private key received from the gate controller matches the random number for the one of a group consisting of the core module controller and the trusted platform module previously sent to the gate controller;
• the core module controller comprises logic for using session key to communicate with gate controller responsive to verifying the random for the gate controller in the message signed by the private key received from the gate controller matches the random number previously received from the gate controller and the random number for one of a group consisting of the core module controller and the trusted platform module in the message signed by the private key received from the gate controller matches the random number for the one of a group consisting of the core module controller and the trusted platform module previously sent to the gate controller.

An apparatus, comprising:

• a gate operable to move between a closed position and an open position;
• a rotating magnet coupled with the gate;
• two fixed sensors that provide signals based on a position of the rotating magnet;
• and
• a controller coupled with the two fixed sensors, the controller is operable to determine a position of the gate based on signals from the sensor and to determine whether a motor operable to move the gate is running;
• wherein the controller determines a tampering event responsive to detecting movement of the gate when the motor is not running;
• and
• the controller is operable to take corrective action responsive to determining the tampering event.

An apparatus, comprising:

• a cassette for storing currency notes;
• a gate;
• a shuttle operable to convey currency notes from the cassette to the gate;
• a transport path for conveying currency notes from the cassette into the shuttle;
• a light pipe sensor operable to detect currency notes withdrawn from the cassette;
• a double detector at an end of the transport path adjacent to the shuttle;
• a plurality of shuttle entry sensors operable to detect notes entering the shuttle;
• a divert/retract cassette;
• a shuttle entry gate operable to selectively direct notes to the shuttle or the divert/retract cassette;
• and
• a controller that is operable to control the shuttle entry gate, the controller is coupled with the light pipe sensor, the double detector, and the plurality of shuttle entry sensors;
• wherein the controller is operable to operate the shuttle entry gate based on signals received from the light pipe sensor, the double detector, and the plurality of shuttle entry sensors.
