| Outline of Final Research Achievements |
PUF, Fuzzy extractor, and authentication protocol were comprehensively examined so that the authentication protocol can be executed by sensor devices with low computational resources. Programmable analog ICs on which analog front-end circuits for sensors are implemented can be used as PUF. We proposed a secret sharing method on an integer ring as a tool for Fuzzy extractors, and showed Fuzzy extractors using NTRU public-key cryptosystem. The lightweight block cipher required for authentication protocols was implemented in FPGA from C language programs by high-level synthesis, and the relationship between the description in C language and power consumption was investigated.

| Academic Significance and Societal Importance of the Research Achievements |
アナログ回路の設計開発の効率化のために開発されたプログラマブルアナログICがPUFとして利用できることはアナログフロントエンド回路を必要とするセンサに都合がよい。Fuzzy extractorは雑音除去のために誤り訂正符号を使った構成法がよく知られているが、NTRU暗号を利用すると、雑音除去だけでなく、固有情報の機密性が暗号学的に保証できる長所がある。
