| Research Abstract |
This project worked on how to share a secret key between communication parties. To enhance the security, we assumed an eavesdropper located nearby and estimate correlation between the keys generated in the eavesdropper and in regular terminals. We proposed a new technique on smart antenna structure and signal processing procedure that can reduce such correlation. We also carried out an experiment where the concept was successfully proved.
