Abstract
In this paper a new method of establishing secret
keys for wireless communications is proposed. A retrodirective
array (RDA) that is configured to receive and re-transmit at
different frequencies is utilized as a relay node. Specifically the
analogue RDA is able to respond in ‘real-time’, reducing the
required number of time slots for key establishment to two,
compared with at least three in previous relay key generation
schemes. More importantly, in the proposed architecture equivalent
reciprocal wireless channels between legitimate keying nodes
can be randomly updated within one channel coherence time
period, leading to greatly increased key generation rates (KGRs)
in slow fading environment. The secrecy performance of this RDA
assisted key generation system is evaluated and it is shown that
it outperforms previous relay key generation systems.
