Abstract
In a data-sending device, a data generation section provides input data itself or a bit-inverted version of the input data as intermediate data and generates an inversion signal that indicates whether or not the intermediate data is the bit-inverted version of the input data. An encrypting section generates scrambled data by inserting the inversion signal in the intermediate data at a bit position. A data-receiving device removes the inversion signal from the scrambled data, and restores the input data based on the inversion signal.
