“…It is not difficult to find that the secret key generation rate of the MR scheme can be improved with the increase of i when other parameters are fixed. Figure 5 illustrates the secret key generation rates against h 0 using the proposed scheme, Xiao's scheme [26], Lai's scheme [15], and the conventional scheme without relay nodes. Without loss of generality, we assume T = 10, T 0 = 1, 2 = 2 0 = 2…”

“…This is because in the proposed scheme, as T increases, Alice and Bob could send more random signals and thus the correlated information obtained by them increases. Figure 7 illustrates the cooperative secret key generation rates against the number of relays N using the proposed scheme, Xiao's scheme [26] and Lai's scheme [15]. In this test, we assume T = 12, T 0 = 1, 2 = 2 0 = 2 A = 2 B = 2 R i = 3, P A = P B = 3, h 0 = 0.78.…”

This paper focuses on high efficiency secret key generation mechanism of physical-layer communication over fading channels in ubiquitous wireless networks. The secret key rate via traditional physical-layer approach could be limited when the wireless propagation channels connecting two sensors change slowly. To generate a high-rate secret key and improve the communication efficiency over quasi-static block fading channels, a novel multi-randomness device-to-device secret key generation strategy and a cooperative communication mechanism aided by relay nodes are proposed. In the proposed schemes, the legitimate members to send random signals rotationally in every coherent time T are set; thus, two legitimate ubiquitous wireless network members, Alice and Bob, can obtain the potential correlated information by exploiting the randomness and the reciprocity of the wireless propagation channels. Considering the reciprocity of wireless channels is variable while the forward channel gain and backward channel gain are correlated in coherent time, a modified secret key generation scheme is proposed via layered coding with theoretical secret key rates derived. The simulation results show that the proposed scheme outperforms traditional approaches with favourable application prospects in ubiquitous wireless communications networks and internet of things.

“…However, in static environment, such as the Internet of things (IoT) system, the channel varies slowly, which leads to low secret key rate. Existing work has taken some measures to improve the secret key rate, such as relay aided [1] and user-introduced randomness[2] [3] aided SKG schemes. However, to conduct these methods, additional trusted collaboration nodes or the redesigned communication protocols are needed, which is difficult in practical application.…”
