“…l,m denotes the cumulative inter-interference from the co-channel D2D-V transmitters to the m-th D2D-V receiver. Note that all the V2X communication channels are impaired by additive Gaussian noise with variance N 0 [38]. In this paper, we are centered on the interference-limited C-V2X computation-offloading network, where the power of thermal noise N 0 would be negligible compared to the inter-tier and cross-tier aggregate interference [33], [39].…”

In a cellular vehicle-to-everything (C-V2X) enabled computation-offloading network, vehicular users may deliver computation tasks to a cellular base station (BS) through vehicle-to-infrastructure (V2I) transmission links in order to accommodate computation-intensive applications, where the BS is usually equipped with a mobile edge computing (MEC) server. However, due to the broadcast nature of wireless communications and high-mobility of vehicles, the computation-offloading information may suffer from an eavesdropping threat. In practice, the interference generated by device-to-device-based V2V (D2D-V) links can be utilized for protecting the offloading information against eavesdropping. This observation motivates a security provisioning for C-V2X computation-offloading network. Specifically, a dynamic thresholdbased access scheme is required to maintain the interference under control for different channel conditions. Unfortunately, the previous studies that are based on the assumption of perfect channel state information (CSI) can not be applied for the dynamic vehicular networks. In this paper, we propose a dynamic thresholdbased access scheme for security provisioning of C-V2X computation-offloading network by considering an imperfect CSI. In this scheme, an optimized access threshold is set to update adaptively in terms of channel estimation error for balancing both the security and reliability of the offloading link. Furthermore, the proposed scheme can maximize the secrecy throughput under a connection outage constraint of the D2D-V links, with the total area spectral efficiency optimized under the security performance criterion for the offloading link. Numerical results are provided for validating the proposed theoretical analysis. A useful design insight is provided for attaining an optimal configuration of C-V2X computation-offloading network.

“…Therefore, while improving the spectral efficiency of the cellular network, the signal interference coming from cellular users does not impact on the D2D communication link . It is also assumed that all D2D pairs in the network that may use the same spectrum as the D2D pair share this spectrum orthogonally; therefore, the interference of other D2D pairs on the intended D2D pair is neglected …”

In this paper, the physical layer security is studied in device‐to‐device (D2D) communications overlaying cellular network where a D2D pair communicates with each other through an untrusted amplify‐and‐forward (AF) relay. Meanwhile, an untrusted relay acts as an eavesdropper in the network. In addition, a jammer is used to create secure communications between D2D pairs. To obtain ergodic secrecy rate (ESR), two scenarios of without jammer (WoJ) and with jammer (WJ) are investigated. In both scenarios, first, the optimal power allocation (OPA) problem is formulated and solved, and then, new closed‐form solutions are presented by calculating the ESR. Moreover, for the WJ scenario, the slope and power offset of the ESR in high signal‐to‐noise ratio are evaluated. Simulation results are presented to determine the importance of OPA and using a jammer to improve the ESR. In addition, the effects of increasing the distance between D2D pairs with each other and with untrusted relays are investigated. The simulation results validate our closed‐form expressions and show that the ESR improves with OPA, and the ESR of the WJ scenario is higher than the WoJ scenario.

We study transmitter authentication in massive multiple-input multiple-output (MIMO) systems with non-ideal hardware for the fifth generation (5G) and beyond networks. A new channel-based authentication scheme is proposed by taking hardware impairments into account. Based on signal processing theory, we first formulate channel estimation under hardware impairments and determine error covariance matrix to assess the quantity caused by hardware impairments on authentication performance. With the help of hypothesis testing and matrix transformation theories, we are then able to derive exact expressions for the probabilities of false alarm and detection under different channel covariance matrix models. Extensive simulations are carried out to validate theoretical results and illustrate the efficiency of the proposed scheme. Impacts of system parameters on performance are revealed as well.
