In this paper, we develop novel Automatic Repeat reQuest (ARQ) key sharing protocols for correlated fading channels. In particular, a novel role of "dumb antennas" in overcoming the negative impact of spatial correlation, on the achievable secrecy rates , is unveiled. We further develop an adaptive rate allocation policy which achieves higher secrecy rates by exploiting the channel temporal correlation. The performance gains offered by the proposed schemes are demonstrated by a comprehensive set of numerical results.
