Recently, most physical-layer based security strategies for Internet of thing tackle the two fundamental issues-authentication and communication key generation. However, the cost of such schemes is often high because of advanced hardware for wireless physical-layer characteristic extraction. In this paper, a lightweight authenticated secret key extraction is proposed based on the frequency-selectivity of multipath fading channels. To perform location-based device authentication and fast secret key extraction, we exploit the received signal strength of multi freqencies. The performance of our proposed method is evaluated with CC1101 IoT nodes, which verifies the feasibility of security strategy on ordinary low cost devices and in static environment.
