| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We consider secret key agreement for multiple terminals based on radio propagation characteristics in a wireless relaying system where more than two terminals communicate with each other via a relay. In this system, the multiple terminals share a common secret key generated from their radio propagation characteristics with the help of the relay in the presence of an eavesdropper. In this paper, we present three secret key agreement schemes: an amplify-and-forward (AF) scheme, a signal-combining amplify-and-forward (SC-AF) scheme, and a multiple-access amplify-and-forward (MA-AF) scheme. The basic idea of these schemes is for all the terminals to share a fading coefficient between each terminal and the relay, and use it as the source of a secret key. Simulation results show that the SC-AF and MA-AF schemes are effective, but the AF scheme is not if the eavesdropper is located near the relay and can receive signals from the relay without multipath fading and noise. | |
