Claim of US Patent No. 9,760,731

1. A configurable data guard (CDG) implemented on a hardware-based programmable logic device, the CDG comprising:
a first network interface configured to receive data;
a first integrated circuit portion of the hardware-based programmable logic device, the first integrated circuit portion comprising
a plurality of arrays of preconfigured comparison operations;

a second integrated circuit portion of the hardware-based programmable logic device, the second integrated circuit portion
comprising a plurality of arrays of preconfigured action operations;

a microprocessor configured to:
receive a data guard configuration,
perform an authentication and integrity check procedure on the received data guard configuration, and
configure a plurality of guard primitives based on the data guard configuration, wherein each guard primitive is configured
from at least one preconfigured comparison operation from the first integrated circuit portion and at least one preconfigured
action operation from the second integrated circuit portion; and

a second network interface configured to output the data after the data has been processed by the plurality of guard primitives.
