“…As defined in previous works [ 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ], secrecy capacity is the maximum rate at which the destination can decode the packets, while the eavesdropper’s bit error probability of decodes approaches one. Here, we will derive the closed-form expressions of average secrecy rate (ASR) based on the fading characteristic of the Rayleigh fading channel.…”

“…Note that the aforementioned works mainly focus on the aspects of transmission strategy design [ 28 ], performance optimization algorithm [ 29 , 30 ], resource management [ 31 , 32 , 33 ], and few works have investigated the secrecy performance analysis of CSRNs. Different from [ 23 , 34 ], this paper investigates the physical layer security performance of CSRNs with an EH-based enemy fusion center, wherein, due to the PU’s interference temperature constraint, the transmit power of the secondary sensor transmitter (ST) is largely restrained, which has greatly affected the system transmission performance of the secondary sensor network.…”

Security and privacy are crucial for cognitive sensor radio networks (CSRNs) due to the possible eavesdropping between secondary sensors and the secondary fusion center. Motivated by this observation, we investigate the physical layer security performance of CSRNs with an external energy harvesting (EH)-based eavesdropper. Considering the underlay working paradigm of CSRNs, the transmit power of the secondary sensor node must be adjusted to guarantee the quality-of-service (QoS) of the primary user. Hence, two different interference power constraint scenarios are studied in this paper. To give an intuitive insight into the secrecy performance of the considered wiretap scenarios, we have derived the closed-form analytical expressions of secrecy outage probability for both of the considered cases. Monte Carlo simulation results are also performed to verify the theoretical analysis derived, and show the effect of various parameters on the system performance.
