Pay at pump encryption device
Embodiments of the present invention are drawn to systems and methods for securing information using cryptographically keyed units. Specifically, in one embodiment of the present invention, a system is provided for securing information that uses two cryptographically keyed units to encrypt information flowing between a fuel pump device and a remote device. Thus, even if the information is intercepted, it could not be used to perpetrate fraud.
1. A system, comprising:
a fuel pump comprising:
a fuel pump housing, a tamper sensor, a fuel pump device, and a first cryptographically keyed unit (“CKU”), the fuel pump housing encloses or houses: the tamper sensor, the fuel pump device, and the first CKU;
a remote device comprising a second CKU, wherein the remote device is external and remote from the fuel pump;
a first connection comprising a physical wired bus connection between the fuel pump device and the first CKU; and
a second connection comprising an unsecured connection between the first CKU and the second CKU;
wherein the first CKU comprising a first processor;
wherein the first processor of the first CKU comprising a secure authentication module circuit, and the first processor programmed to: receive consumer information input into the fuel pump device over the first connection as payment information and encrypt the consumer information using the secure authentication module circuit yielding encrypted consumer information;
wherein the second CKU comprising a second processor;
wherein the second processor of the second CKU programmed to: receive the encrypted consumer information from the first CKU over the second connection, decrypt the encrypted consumer information yielding output information, and provide the output information to the remote device for payment processing;
wherein the tamper sensor comprising at least one of an open door sensor, a motion sensor, a light sensor, and an echo-cavitation sensor, wherein the tamper sensor is configured to detect tampering with the fuel pump, the fuel pump housing, the fuel pump device, or the first CKU, wherein the tamper sensor is further configured to generate and trigger sensor information upon tampering;
wherein the fuel pump device is configured to be disabled when the sensor information is triggered from the tamper sensor.
2. The system of claim 1 , wherein the first connection and the second connection each use at least one of a current loop, RS485, RS422, RS232, or LON communications protocol.
3. The system of claim 1 , wherein the remote device is at least one of another CKU, a point-of-sale terminal, a fuel pump device, or a site controller.
4. The system of claim 1 , wherein the first CKU further comprises a memory.
5. The system of claim 4 , wherein the memory retains a log comprising the sensor information from said tamper sensor.
6. The system of claim 1 , wherein the output information comprises at least one of consumer payment information or consumer identify information.
7. The system of claim 1 , wherein the first processor and the second processor utilize one of a symmetric encryption algorithm or an asymmetric encryption algorithm.
8. The system of claim 1 , further comprising an enclosure that contains the first CKU, wherein the enclosure is located within the fuel pump housing.
