“…BDs and potential attackers could be static and mobile. All BDs within the coverage of one AP alternately perform backscatter transmission in a time-division manner, as designed in prior arts [2], [4], [5], [43]. In each slot of time, the AP selects only one BD by signaling, making the RF signals backscattered only from this BD without mutual interference at the receiver AP.…”

Backscatter communication (BC) enables ultra-lowpower communications and allows devices to harvest energy simultaneously. But its practical deployment faces severe security threats caused by its nature of openness and broadcast. Authenticating backscatter devices (BDs) is treated as the first line of defense. However, complex cryptographic approaches are not desirable due to the limited computation capability of BDs. Existing physical layer authentication schemes cannot effectively support BD mobility, multiple attacker identification and attacker location tracing in an integrated way. To tackle these problems, this paper proposes BCAuth, a multi-stage authentication and attack tracing scheme based on the physical spatial information of BDs to realize enhanced BD authentication security for both static and mobile BDs. After initial authentication based on BD identity with its position information registration, preemptive authentication and re-authentication are performed according to spatial correlation of backscattered signal source locations associated with the BD. By exploiting clustering-based analysis on spacial information, BCAuth is capable of determining the number of attackers and localizing their positions. In addition, we propose a reciprocal channel-based method for BD reauthentication with better authentication performance than the clustering-based method for mobile BDs when the BDs is able to measure received signal strength (RSS), which also enables mutual authentication. We theoretically analyze BCAuth security and conduct extensive numerical simulations with various settings to show its desirable performance.

Here, the energy harvesting (EH) relaying node which needs to complete the simultaneous wireless information and power transfer (SWIPT) is considered. The EH relaying node uses the EH technique to get the energy supply and uses the directional transmission to improve the performance of SWIPT. The double discrete‐time‐switch (D‐DTS) based energy harvesting–power transfer–information transmission (EH–PT–IT) protocol is designed. One of the discrete‐time‐switch (DTS) controls the receiver of the EH relaying node and the other controls the transmitter. The performance is analysed by considering the average information rate and the average transferred power. The expressions of the average information rate and the average transferred power are derived analytically. The balanced maximization is considered, and the optimal parameters are obtained analytically. The simulations are presented to verify the analytical results and compare the performance. Comparing with previous works, the SWIPT performance using D‐DTS protocol in this work is better.
