Abstract

Schemes for secret key agreement based on the radio transmission path characteristics between authorized stations have been proposed as anti-eavesdropping measures in land mobile radio. In this paper, we propose a new scheme for secret key agreement. It compares the strengths of the signals received at two antennas to produce a bit of the keys. It does not use a threshold which is used in the conventional schemes. We evaluate the performance of the proposed scheme by computer simulation.
