Abstract
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.
Claims12
A non-transitory computer readable medium comprising a computer program, which when executed by a processor performs a method, the method comprising:
- processing a data message to extract segments of data;
- 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;
- 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.
A non-transitory computer readable medium comprising a computer program, which when executed by a processor performs a method, the method comprising:
- processing the datastream to extract a checksum and a data message;
- processing the data message to extract segments of data;
- applying a gray code conversion to one or more of the data segments to compute a validation checksum;
- and
- comparing the validation checksum with the extracted checksum.
