Outline of Annual Research Achievements

本研究は、複数の任意の高機能暗号方式における暗号文変換および方式の組み合わせ変換が可能とする「アジャイルクリプト技術」の実現を目指す。今年度の代表的な成果は以下である。
- 秘密計算という、情報を秘匿したままデータ解析ができる技術に関して、様々な成果が得られた:秘匿回路の秘密計算の高安全化(国際論文誌Designs, Codes and Cryptography)、Private simultaneous messagesプロトコルの高度化・高効率化の変換(国際会議EUROCRYPT24、国際論文誌Designs, Codes and Cryptography)、秘密計算の様々なクラスの下界(国際会議ITC23、ACNS23、INDOCRYPT23)、カードベースプロトコルの高効率化(国際会議IWSEC23)、秘匿かつ検証可能な機械学習プロトコルの提案(国際会議ACNS24)。
- 高機能暗号について、様々な成果が得られた:関数暗号の高度化(国際会議EUROCRYPT23-2件、CRYPTO23)、電子署名方式の高度化・高効率化(国際会議FC23、ASIACRYPT23、国際論文誌IEICE)、生体認証方式の組み合わせ変換(国際会議IJCB)、準同型暗号の高度化(国際論文誌IEICE)。
