This paper studies the secondary network relying relay selection to transmit signal from the secondary source (base station) to two destinations. Especially, two destinations are required non-orthogonal multiple access (NOMA) scheme and it benefits to implementation of the Internet of Things (IoT) systems. However, eavesdropper over-hears signal related link from selected relay to destination. This paper measure secure performance via metric, namely secure outage probability (SOP). In particular, signal to noise ratio (SNR) criterion is used to evalute SOP to provide reliable transmission to the terminal node. Main results indicates that the considered scheme provides performance gap among two signals at destination. The exactness of derived expressions is confirmed via numerical simulation.

“…First, cooperation from relays was introduced to avoid (or to mitigate) the wiretapping region (or its impact) [3,4,[13][14][15][16][17][18][19][20][21][22]. In these works, the directlink from the source to the eavesdropper is usually not closed to the source.…”

This article resolves an extreme case in physical layer security: an eavesdropper, located near to a source, can spy on the jamming-seed if it is just cryptographically shared. The direct link between the source and destination is even unavailable. The system is proposed to operate in triple transmission phases (timeslots). In the first phase, jamming signal is proposed to carry a random binary network-coding-based jamming (NCJ) message, transmitted by an active jammer. As NCJ cannot be just cryptographically protected, we propose a solution of using physical layer security to secure this message. As a result, a network-coding method can be employed in which NCJ acts as a key to protect the source message from this extreme case of wiretapping. The spatial diversities in both jamming and legitimate transmission is fully exploited to overcome this challenge with high performance. Analysis and simulation of the outage performance and comparison with current methods are provided to validate the performance of the proposed method.

“…The DF scheme requires the relay to decode the source message whose performance mainly relays on the source-relay channel (e.g., [19], [20], [25]- [27]). The AF scheme arranges the relay node to scale and retransmit the received signal (e.g., [25], [28]- [30]). Deaf cooperation arranges the relay to send interference (or pure noise) which is independent of the source message in order to confuse the eavesdropper (e.g., [4], [18], [21], [22], [29]- [33]).…”

In this paper, we consider the design of a new secure transmission scheme for a four-node relay-eavesdropper channel, where user cooperation is used to facilitate secure communications. The key idea of the proposed achievable scheme is to apply the compression relaying concept of noisy network coding (NNC) to the secrecy communication scenario. But different to the original non-secrecy NNC, the compression rate at the relay is adaptively chosen according to the eavesdropping channel. Particularly, helping interference information is injected into the compression codebook at the relay by simply enlarging the compression rate, which is to effectively suppress the eavesdropping channel. Closed-form expressions of the secrecy rates achieved by the proposed NNC-based secure scheme are characterized for both the discrete memoryless and Gaussian relay-eavesdropper channels, where the optimal compression rate and the optimal transmit power at the relay are also determined. The proposed secure scheme can be viewed as a general framework, which naturally combines the NNC compression relaying scheme with the interference-assisted scheme. Analytical and numerical results demonstrate that the proposed secure scheme offers constant performance gains over typical existing cooperative secure schemes.
