Abstract
Using three pieces of element data w, w, and wobtained by partitioning storage data D, an encryption unit generates three sets of a first set Ain which the first to third pieces of element data are sequentially arranged, a second set Ain which the second to third pieces of element data are sequentially arranged, and a third set Acomposed of the third piece of element data. The encryption unit encrypts each piece of element data included in each set with a random number Rby a CBC mode.
