Abstract
Processing for generating a plurality of pieces of distributed data from original data or processing for restoring original data from a plurality of pieces of distributed data is performed safely and quickly. A distribution and restoration apparatusgenerates a plurality of pieces of distributed data SDto SDby dividing original data OD into a plurality of divided blocks DBto DBand performing an operation of exclusive OR using divided blocks of different combinations. A combination including divided blocks used in common in a plurality of pieces of distributed data and a combination including divided blocks used only in specific distributed data are present in combinations of divided blocks in each piece of distributed data. Therefore, the distribution and restoration apparatuscan generate a plurality of pieces of safe distributed data having high information entropy at high speed.
