Abstract:

An integrated physical-layer security scheme is proposed, which combines dynamic physical-layer secret key generation (SKG) and static device fingerprint authentication (DFA) for secure transmission in frequency division duplex (FDD) systems. The proposed approach employs random forest (RF) algorithms to achieve high-speed SKG and utilizes autoencoders (AE) to realize high-accuracy DFA. Besides, channel interference to DFA is minimized during the integration. Experimental results demonstrated that the SKG achieved a key generation rate (KGR) of 57.71 Kbps, while the open-set DFA recognition accuracy reached 99.60%, with a miss alarm rate (MAR) of 0.93%. The proposed scheme successfully integrates physical-layer identity recognition and a fast key generation with excellent performance.
