Toward Proper Guard Zones for Link Signature

Abstract

Toward Proper Guard Zones for Link Signature Motivated by information theoretical security, link signature (LS)-based security mechanisms exploit the broad channel characteristics for security establishment between wireless devices.

However, such an assumption may not hold universally-for much larger spatial separations, high channel correlations were observed in some environments. To this end, various well-established models of channel correlation are investigated in this work.

A set of important physical factors that have a significant influence on LS safety are identified and extensive simulations are conducted with the insights obtained to explore suitable LS guard zone sizes in several typical indoor and outdoor environments. Also presented to further support the analysis are experimental results based on universal peripheral software radio (USRP) platforms and GNURadio.

In this paper, we planned distributed energy-efficient clone detection protocol with random witness choice. We also evaluate the mimicry attacks on the USRP2 platform running GNURadio and the time-synchronized link signature scheme.
