 note = {我が国の科学技術政策に伴い，デジタル社会インフラの基盤技術とそのサイバーセキュリティ対策がますます重要となってきている．産業分野のハードウェアデバイスに対しては，最先端の暗号技術を適用するだけでなく，サイドチャネル攻撃やハードウェアトロイの脅威への対策を併せ持つ実装技術の確立が必須である．そこで，我々は低遅延動作可能な軽量ブロック暗号 SuperSonic と機器認証用グリッチ PUF を組合せた SuperSonic-GPUF を提案してきた．一方で，従来の SuperSonic-GPUF は認証用 ID の安定性が不十分であることから，大型の誤り訂正用回路が必要となるため，産業用デバイスへの実装の課題が残されている．こうした背景から，本研究は SuperSonic-GPUF の認証性能について詳細な評価実験を行うとともに，認証性能を改良可能な実装方式を提案する．評価実験では，SuperSonic-GPUF のチャレンジ信号には第 2 ラウンド関数の暗号中間値を用いることで認証性能を改善できることを明らかにした．, In accordance with the basic plan for science and technology in Japan, The fundamental technologies of digital social infrastructures and their cybersecurity countermeasures have become very important. For industrial hardware devices, it is essential not only to apply state-of-the-art cryptographic techniques but also to implement countermeasures against threats such as side-channel attacks and hardware trojans. Thus, We have proposed SuperSonic-GPUF, which is a combination of SuperSonic, a lightweight block cipher with low latency, and glitch PUF for device authentication. On the other hand, conventional SuperSonic-GPUF has some implementation issues, such as the need for a large error correction circuit due to insufficient stability of the authentication ID. Against this background, this study evaluates the authentication performance of SuperSonic-GPUF in detail and proposes an implementation method that can improve the authentication performance. The evaluation experiments in this study revealed that the optimal challenge signal for the SuperSonic-GPUF is the cryptographic intermediate value after in the second round function.},
