A non-transitory computer readable medium includes a computer program, which when executed by a processor performs a method, the method including processing a data message to extract segments of data and computing a checksum by applying gray code conversions to one or more of the data segments, wherein only one bit changes on each count when consecutive integers are represented as bits. The method further includes extracting remaining data segments and adding bitwise to the previously calculated gray code checksum to provide the next checksum, converting the next checksum to gray code, and adding a final gray code conversion to a final data message including all remaining data segments and transmitting the final data message.
