Abstract
Methods for configuring and utilizing a configurable data guard (CDG) implemented on a hardware-based programmable logic device are disclosed. The CDG may include integrated circuit portions comprising a plurality of arrays of generic comparison operations and a plurality of arrays of generic action operations. The CDG may receive a data guard configuration. The CDG may perform an authentication and integrity check procedure on the received data guard configuration. The CDG may configure a plurality of guard primitives based on the data guard configuration. Each guard primitive may be configured from at least one generic comparison operation and at least one generic action operation. The guard primitives may be used to enforce the complex data guard rules that correspond to the data guard configuration.
