多跳无线网络的端到端（E2E）物理层认证目前还没有得到很好的研究。作为这一方向的一步，本文重点研究了具有不可信中继的双跳无线网络中的E2E物理层认证，并提出了相应的物理层认证方案。该方案充分利用了级联信道的幅度和延迟间隔的位置特定性，并采用了人工干扰技术，不仅能抵抗来自未授权发射机的冒充攻击，还能抵抗来自不可信中继的重放攻击。进一步进行理论分析，推导出虚警概率和漏检概率的表达式，这是认证性能的两个基本指标。最后，数值和仿真结果表明，这些理论结果的有效性和E2E认证性能的双跳无线网络下所提出的计划。
End-to-end (E2E) physical layer authentication for multi-hop wireless networks is still not well-explored by now. Like one step forward in this direction, this paper focuses on the E2E physical layer authentication in a dual-hop wireless network with an untrusted relay and proposes a corresponding physical layer authentication scheme. The scheme fully utilizes the location-specific features of both channel amplitude and delay interval of cascaded channels and adopts the artificial jamming technique, so that it is not only resistant to the impersonate attack from an unauthorized transmitter but also resilient to the replay attack from the untrusted relay. Theoretical analysis is further conducted to derive the expressions for the probabilities of false alarm and missed detection, which are two fundamental metrics of authentication performance. Finally, the numerical and simulation results are provided to illustrate both the efficiency of these theoretical results and the E2E authentication performance of dual-hop wireless networks under the proposed scheme.
