APPARATUS AND METHOD FOR FAULT DETECTION ON REDUNDANT SIGNAL LINES VIA ENCRYPTION.

摘要

A fault detection apparatus and method combines each of a plurality of redundant digital data signals with a unique key signal for transmission over one of a plurality of signal lines and recombines each with its unique key signal at a receiving end. The recombined signals are then compared at the receiving end to detect certain faults between or among the plurality of what should be identical received signals.
