A secure computation apparatus (1) obtains a secret value representing a result of divided N by D using a secret value [N] of a real number N and a secret value [D] of a natural number D. An initialization unit (12) sets a secret value [PL1] of a partial remainder PL1 to 0. A parallel comparison unit (13) computes secret values [E1], . . . , [ER−1] of comparison results E1, . . . , ER−1 of comparing a secret value [n] of a partial divisor n=Pj+1R+Nj with [D]×g for each integer g not less than 1 and less than R in parallel. An update unit (14) computes a secret value [Qj] of a quotient Qj and a secret value [Pj] of a partial remainder Pj that satisfy n=DQj+Pj using the secret values [E1], . . . , [ER−1] of the comparison results E1, . . . , ER−1. An iterative control unit (15) executes the parallel comparison unit (13) and the update unit (14) for each integer j from L1−1 to −L0."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secure division system, secure computation apparatus, secure division method, and program","description":"Division is realized with a small number of processing stages.
