Outline of Final Research Achievements |
This research is aiming to realize a high-security wireless communication at beyond 5G era. As an encryption for wireless communication, a physically secured wireless communication configuration which deduces ANDed data decrypted from heterodyne detection between two wireless data streams was proposed. As a feasibility experiment, the demonstration of a heterodyne AND operation was conducted by devising an optical system to emulate our novel wireless system. Experimental results testified the principle of our proposed encryption function. The result has been presented at some journals and conferences and received three paper awards.

Academic Significance and Societal Importance of the Research Achievements |
本研究の学術的意義は、高周波電波が有する指向性を利用し、また電波の一般的な受信法であるヘテロダイン検波法の特長を利用して、二つの電波を用いるという新たなアプローチによりセキュア性の高い無線通信の提案と原理検証を行ったことである。さらにそれを実現するための要素デバイスの動作実証を行ったことである。現在普及が進んでいる5Gあるいはさらに将来のBeyond 5Gにおいては、個人情報保護やセキュアな通信が必須であり、この要件を満たす技術の可能性を示したことに社会的意義がある。
