| Outline of Final Research Achievements |
This research proposed and developed a device authorization technique that exploits radio-propagation characteristics (RPCs). Since it does not depend on information processing such as encryption technology, we can apply it resource-restricted devices such as IoT applications. By using our technique, we can detect spoofing attacks targeting wirelessly communicated devices. The most important feature is that our technique makes it possible to define "physical space" by exploiting RPCs and it can be used for many future applications.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の学術的意義は、サイバー空間をフィジカル（物理）現象を用いて守る、という点にある。基本的に物理現象は改ざん不可能であり、これをより所とすることで、いわゆる攻撃者と防御者のイタチごっこに終止符を打つことができる可能性がある。今後は無線接続されたデバイスを搭載したシステムの普及が予想され、これらに対し本技術を適用することができる。
