Power Analysis Attack on Jamming Assisted Key Agreement
Proceedings of 2017 the 7th International Workshop on Computer Science and Engineering · 2017
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.
