Abstract
A method for performing high-integrity data transmission is provided. The method obtains a first set of data at a first transmitter and a second set of data at a second transmitter; develops a first key for the obtained first set of data and a second key for the obtained second set of data; and when the first key matches the second key, provides a receiver indication of validity of the first set of data. In certain embodiments, the method stores the first key and the second key within a predetermined window of time. In some embodiments, when the first key matches the second key, the method also synchronizes operation of the first transmitter and the second transmitter.
