Physical-Layer Identification of Power Line Communications Using WS-DNA Fingerprinting
Vulnerabilities in networked systems can leave critical infrastructure exposed to cyber attacks and short falls in home automation communication security permit similar attacks against government personnel. PLC as a network communication method is a cost effective solution supporting many of these networks. Global time synchronization can allow a SPN of multiple interconnected devices to transmit repeated signals simultaneously which can increase operating range and reliability. PLC device and SPN discrimination using WS-DNA fingerprinting is investigated for PHY intrusion detection. 6 Insteon Hubs are used for single device DUT discrimination. The same 6 Insteon Hubs are integrated with 4 different Insteon On/Off Outlets to create 24 distinct SPNs that are used in SPN DUT discrimination. For single device DUT, an average C = 90 is achieved at SNR 36 dB. ROC curves are used to illustrate rogue detection results with EER of 10 achieved for all devices at SNR = 40 dB. For the SPN DUT subset an average of C = 90 is achieved for SNR 50 dB with rogue detection resulting in a EER = 10 achieved at SNR = 50 dB.
