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.
