LEO卫星星座的物理层认证

Physical Layer Authentication for LEO Satellite Constellations

Ozan Alp Topal, Gunes Karabulut Kurt

摘要:

物理层认证(PLA)是基于节点的物理层特性(例如信道衰落或硬件缺陷)来声明节点的身份的过程。在这项工作中,我们提出了一种新的PLA方法的低轨卫星的星际通信链路(ISL)。在建议的PLA方法中,多个接收卫星通过比较多普勒频率测量值与合法发射机的参考移动性信息来验证发射机的身份,然后考虑所选择的决策规则来融合它们的决策。给出了融合方法的欺骗检测概率和虚警概率的解析表达式。数值上获得的高认证性能的结果铺平了道路,一种新的,易于集成的认证机制的LEO卫星网络。

英文摘要:

Physical layer authentication (PLA) is the process of claiming identity of a node based on its physical layer characteristics such as channel fading or hardware imperfections. In this work, we propose a novel PLA method for the inter-satellite communication links (ISLs) of the LEO satellites. In the proposed PLA method, multiple receiving satellites validate the identity of the transmitter by comparing the Doppler frequency measurements with the reference mobility information of the legitimate transmitter and then fuse their decision considering the selected decision rule. Analytical expressions are obtained for the spoofing detection probability and false alarm probability of the fusion methods. Numerically obtained high authentication performance results pave the way to a novel and easily integrable authentication mechanism for the LEO satellite networks.
