1. A method for securing information using cryptographically keyed units, comprising the steps of:
- a. receiving at a first cryptographically keyed unit (“
CKU”
) consumer information from a fuel pump device over a first connection, said first CKU comprising a first processor, said consumer information comprising at least one of consumer payment information or consumer identity information;
b. encrypting the consumer information by the first processor;
c. transmitting the encrypted consumer information from the first CKU to a second CKU over a second connection, said second CKU comprising a second processor, wherein the second connection is unsecured;
d. receiving and decrypting the encrypted consumer information by the second processor to produce the consumer information; and
e. communicating the consumer information from the second CKU to a remote device.

Abstract
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.

17. A method for securing information using cryptographically keyed units, comprising the steps of:
-
a. receiving over a first connection at a first cryptographically keyed unit (“
CKU”
) payment information from a fuel pump device located within a fuel pump housing, wherein the first CKU comprises a first processor and is located in an enclosure installed in the fuel pump housing;b. encrypting the payment information by the first processor to create encrypted information; c. transmitting the encrypted information from the first CKU to a second CKU over a second connection, said second CKU comprising a second processor; d. receiving and decrypting the encrypted information by the second processor to produce the payment information; e. communicating the payment information from the second CKU to a remote device; f. monitoring by the first CKU one or more sensors for an indication that at least one of the fuel pump device, the fuel pump housing, or the enclosure has been tampered with, wherein a sensor is at least one of an open door sensor, motion sensor, echo-cavitation sensor, or light sensor; and g. disabling operation of one or more fuel pump devices upon determining by the one or more sensors that there has been tampering with at least one of the fuel pump device, the fuel pump housing, or the enclosure. - View Dependent Claims (18, 19, 20, 21, 22)

23. A method for retrofitting a fuel pump to provide for secure communications, the method comprising the steps of:
-
a. mounting a first encryption device in a housing of the fuel pump, wherein the fuel pump comprises a fuel pump device that communicates with a remote device through a communications channel; b. inserting the first encryption device in the communications channel between the fuel pump device and the remote device, wherein the first encryption device encrypts consumer information being sent over the communications channel from the fuel pump device to the remote device, said consumer information comprising at least one of consumer payment information or consumer identity information; and c. inserting a second encryption device in the communications channel between the first encryption device and the remote device, wherein the second encryption device decrypts consumer information received from the first encryption device and communicates the decrypted information to the remove device. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32)
