| Research Abstract |
This study outputs four significant results.
(1) We proposed Reactance Domain Correlation (RDC) in order to enhance secrecy of wireless secret key agreement systems, and showed effectivity of RDC. (2) We clarified the relation between ESPAR antenna structure and the system secrecy by employing RDC. (3) We designed and prototyped a USB stick size ESPAR antenna for the system, and integrated the antenna, transceiver, USB interface, and system control unit on a printed circuit board. We implemented all of them to work in plug and play on a laptop PC. (4) The system generates and shares the secret key of 128 bits in length within 45 seconds on indoor environment.
