Realize the IC designprotection and the IC authenticity verification throughthe Security-by-Design approach

Semiconductors (ICs) play an important role in supporting the information society, such as communication technology and energy supply. When an outside company is involved in the manufacturing of ICs, the threat of IC design technology leakage and unauthorized products (unauthorized manufacturing, counterfeit products, etc.) is unavoidable. In addition, since the distribution of unauthorized products can lead to problems that cause damage to users, it is vital to have a system that can confirm that the products have passed through the authorized IC manufacturing route.

In this project, we will extract and formalize the security requirements of the entire IC supply chain, which is the infrastructure for Society 5.0, and develop a new IoT system design scheme that collectively realizes the protection of IC design technology and the verification of IC authenticity, i.e., verifying whether the product has passed through the legitimate manufacturing route, by the user. We will realize this scheme satisfying the above security requirements based on the theory of advanced cryptography. We aim to develop a system design method and its design environment to realize this scheme in the security-by-design framework and quantify the trade-off between security levels depending on the use cases of IoT systems and implementation costs.
