Abstract

As de­mons­tra­ted re­cent­ly, Wire­less Phy­si­cal Layer Se­cu­ri­ty (WPLS) has the po­ten­ti­al to offer sub­stan­ti­al ad­van­ta­ges for key ma­nage­ment for small re­sour­ce-cons­trained and, the­re­fo­re, low-cost de­vices, e.g., the wi­de­ly ap­p­lied 8-bit MCU 8051.

In this paper, we pre­sent a fully func­tio­nal test­bed im­ple­men­ta­ti­on to eva­lua­te the per­for­mance and se­cu­ri­ty of Chan­nel-Re­cipro­ci­ty based Key Extrac­tion (CRKE). The test­bed is based on off-the-shelf hard­ware and uti­li­zes the IEEE 802.​15.4 com­mu­ni­ca­ti­on stan­dard for key extrac­tion in re­al-ti­me. The test­bed can in­clu­de mul­ti­ple trans­cei­vers to si­mu­la­te le­gi­ti­ma­te par­ties or ea­ves­drop­per. It con­tains a cen­tra­li­zed con­trol unit which is ca­pa­ble to pa­ra­me­teri­ze the me­a­su­re­ment, e.g., the sam­pling rate, car­ri­er fre­quen­cy, etc., and vi­sua­li­ze nu­me­ri­cal re­sults wi­t­hin a se­cond, e.g., the Pear­son cor­re­la­ti­on, mu­tu­al in­for­ma­ti­on, or secret key rate.

We also pro­po­se a file for­mat for the data of con­se­cu­ti­ve chan­nel me­a­su­re­ments. We be­lie­ve the test­bed and the data for­mat is a good first step to pro­vi­de an easy way to com­pa­re re­se­arch re­sults for the WPLS com­mu­ni­ty. Fur­ther­mo­re, we pre­sent eva­lua­ti­on re­sults of se­ver­al me­a­su­re­ment cam­paigns we per­for­med, while we are fo­cu­sing on at­tack sce­na­ri­os
