Graph Layer Security: Encrypting Information via Common Networked Physics. (arXiv:2006.03568v3 [eess.SP] UPDATED)

The proliferation of low-cost Internet of Things (IoT) devices has led to a
race between wireless security and channel attacks. Traditional cryptography
requires high-computational power and is not suitable for low-power IoT
scenarios. Whist, recently developed physical layer security (PLS) can exploit
common wireless channel state information (CSI), its sensitivity to channel
estimation makes them vulnerable from attacks. In this work, we exploit an
alternative common physics shared between IoT transceivers: the monitored
channel-irrelevant physical networked dynamics (e.g., water/oil/gas/electrical
signal-flows). …
