<p>PROBLEM TO BE SOLVED: To achieve a hash operation circuit having a sequence interchange function without increasing the circuit scale.SOLUTION: An information processor includes: storing means for storing data as a hash operation object; holding means for holding the sequence in which the data is replaced in a predetermined unit; and data feeding means for reading the data in the predetermined unit from the storing means on the basis of the sequence held by the holding means. The data as the hash operation object is stored, the sequence in which the data is replaced in a predetermined unit is held, and the data is read in the predetermined unit on the basis of the sequence.</p> |
