Outline of Research at the Start

本研究では,仮想通貨ネットワークを含む,より一般的なブロックチェーンを基盤とした自律分散型ネットワークにおいて,善良なユーザを保護するとともに,悪意あるユーザを監視できるセキュリティ技術について研究開発を行う.より具体的には,トークンを用いた自律分散型の監視手法を提案するとともに,サイバー攻撃対策と暗号理論の両面で支えられるトークンの高信頼性を確保する.これにより,自律分散型ネットワーク環境において,悪意あるユーザの検出・追跡手法の提案のみならず,高信頼性を持ったトークンによるブロックチェーン基盤のトータルケアを提供する運用方法の確立が期待される.

Outline of Final Research Achievements

In this study, we have conducted research and development on security technologies that can protect good users and monitor malicious users in more general blockchain-based autonomous decentralized networks, including crypto-asset networks. Specifically, we have conducted research and development on three blockchain-related technologies: token-based monitoring, cyber-attack countermeasures, and advanced cryptography. Research achievements during the three-year period from FY 2019 to FY 2021 include four international journals, 20 international conference papers, many domestic symposium papers, as well as student paper awards and encouragement awards at domestic symposiums, and an excellent presentation award at an international conference.

Academic Significance and Societal Importance of the Research Achievements

本研究では,トークンを悪意あるユーザに送信する「しるし」として使用するだけでなく,善良なユーザを保護するためのユーザ証明書のような拡張機能としても使用する.そのようなトークンを用いて実現される自律分散型監視技術は,ブロックチェーンやネットワークのデータから悪意あるユーザを検出し,その取引等を効率的に追跡するのみならず,善良なユーザの信頼性を証明するものである.我々は,自律分散型監視手法を支える技術として,ブロックチェーン,ネットワーク,暗号理論の異なる3つの分野を統合し,トークン利用型監視技術,サイバー攻撃対策技術,及び高機能暗号技術の3つについて包括的な研究を実施した.
