Power Analysis Attack on Jamming Assisted Key Agreement

Qiao HU, Gerhard HANCKE

Abstract— Physical layer key agreement is a trend in wireless communication. But physical layer key agreement schemes utilizing channel state to generate the key has quite low speed. iJam is a novel scheme utilizing assisted jamming signals to generate shared key with much higher speed. We propose a power analysis attack which can break iJam by analyzing the power difference of each received signal. Simulation results show that our attack breaks iJam in most time.

Index Terms— physical layer key agreement, jamming, QAM.
