Outline of Final Research Achievements

In this work, we worked on the authentication data collection before shipping of the authentication technology, PUF(Physical Unclonable Function). PUF technology needs to acquire the authentication data from the fabricated LSIs before shipping the products. In addition, PUFs needed to be protected from the attack to extract the authentication data after shipping.
The feature of this work is adopting BIST(Built-In Self Test) technology, and preventing from exploiting the BIST circuits for the attack after shipping by destroying the BIST circuit after the test before shipping. We proposed the circuit structures of BIST circuit with disabling structure. The PUF circuit including the proposed BIST circuit was implemented on the circuit simulation and operation of the whole PUF circuit was validated on the circuit simulation.

Academic Significance and Societal Importance of the Research Achievements

半導体チップの偽造品はすでに多数流通しており、専門的な報告のみならず、一般市民の目に触れる技術ニュース等でも取り上げられている。本研究成果は単にPUF技術の回路を提案する他の研究とは異なり、PUF技術を実際に実装し、製品に搭載して真贋判定の認証システムを運用する上で重要な役割を果たす。
本研究成果により正規の事業者が十分な量の認証情報の取得し、悪意あるものが認証情報を取得することを防ぐことの両方が同時に実現される。さらに、本手法により十分な量の認証情報を取得することにより、最新の攻撃技術である機械攻撃によるPUFへの攻撃に対しても十分な耐性を得ることが可能となる。
