| Zusammenfassung: | To process encrypted data of a plurality of information terminals more safely.SOLUTION: A secret calculation system comprises: an acquisition part which acquires a plurality of pieces of data to be processed representing data encrypted using a plurality of pieces of different key information generated by a plurality of information processing systems, respectively from corresponding information terminals among a plurality of information terminals; a secret calculation part which generates result data representing results of calculations based upon the plurality of data to be processed with the plurality of data to be processed encrypted; and a providing part which provides the result data for the plurality of information terminals.SELECTED DRAWING: Figure 1
【課題】より安全に、複数の情報端末の暗号化データを処理することを可能とする。【解決手段】複数の情報処理システムで生成される複数の異なる鍵情報を用いて暗号化されたデータを示す複数の処理対象データのそれぞれを、複数の情報端末のうち対応する情報端末から取得する取得部と、複数の処理対象データを暗号化した状態で、複数の処理対象データに基づいて計算した結果を示す結果データを生成する秘密計算部と、複数の情報端末に結果データを提供する提供部と、を備える秘密計算システム。【選択図】図１ |
