ABSTRACT:
The present invention is a method for providing a high-assurance guard in a partitioned processing system, the partitioned processing system including a first input/output partition, a guard function partition and a second input/output partition, the method including the steps of: receiving a data packet from the first input/output partition of the partitioned processing system via a first I/O interface; determining if the data packet is well-formed as defined by an interface control document; and forwarding the data packet to the second input/output partition of the partitioned processing system and to a second I/O interface only when the data packet is well-formed.
