Zusammenfassung:PROBLEM TO BE SOLVED: To provide an information processing device that performs at high speed inner product predicative cipher and function type cipher involving elliptic scalar multiplication and pairing arithmetic.SOLUTION: An encryption processing device 1000 comprises a general purpose computer 200 and a parallel computer 100 for performing parallel processing. The general purpose computer 200 generates input data used by the parallel computer 100 and transmits the generated input data to the parallel computer 100 via communication ports 230 and 130. The parallel computer 100 calculates at least one of elliptic scalar multiplication and pairing arithmetic in parallel by parallel processing using a plurality of processors 111 on the basis of the input data transmitted by the general purpose computer 200.
