Secrecy outage analysis of multi-user cellular networks in the face of cochannel interference

Yuan Heng Jiang, Jia Zhu, Yulong Zou

In this paper, we explore the physical-layer security of a multi-user cellular network in the presence of an eavesdropper, which is made up of multiple users communicating with a base station while the eavesdropper may intercept the communications from users to the base station (BS). Considering that multiple users are available in cellular network, we present three multi-user scheduling schemes, namely the round-robin scheduling scheme, the suboptimal and optimal user scheduling schemes to improve the security of communication (from users to BS) against the eavesdropping attack. In the suboptimal scheduling, we only need to assume that the channel state information (CSI) of the main link spanning from users to BS are known. In contrast to the suboptimal scheduling, the optimal scheduling is designed by assuming the CSI of the main link and wiretap link (spanning from users to the eavesdropper) that are available. We obtain the calculus form of the secrecy outage probability to analyze the secrecy diversity performance. Secrecy diversity analysis is carried out, which shows that the round-robin always achieves only one diversity order, whereas the suboptimal and optimal user scheduling schemes achieve the full diversity order. In addition, the results of the secrecy outage show that the optimal scheduling has the best performance and the round-robin performs the worst in terms of defending against the eavesdropping attack. Lastly, as the number of users increases, both the secrecy outage probabilities of the suboptimal and optimal scheduling schemes have a significant secrecy performance improvement.

Secrecy outage analysis of multi-user multi-eavesdropper cellular networks in the face of cochannel interference

Yuan Heng Jiang, Jia Zhu, Yulong Zou

This paper studies the physical-layer security of a multi-user multi-eavesdropper cellular network , which is composed of multiple users communicating with a base station while the eavesdroppers may intercept the communications from users to the base station (BS). The cellular network is a time-slotted system with simultaneously transmission, in each time slot, a single user is scheduled to transmit messages to BS while the remaining users opportunistically receive information. Considering multiple users available in the cellular network, we present three multi-user scheduling schemes, namely the round-robin scheduling scheme as well as the suboptimal and optimal user scheduling schemes to improve the security of communication (from users to BS) against eavesdropping attacks. We only need to assume that the channel state information (CSI) of the main link spanning from users to BS is known in the suboptimal scheduling. On the contrary, the optimal scheduling is designed by assuming that the CSI of the main link and wiretap link (spanning from users to the eavesdropper) are available. We further carry out secrecy diversity analysis and show that the round-robin always achieves only one diversity order, whereas the suboptimal and optimal user scheduling schemes achieve the full diversity. In addition, numerical results illustrate that the optimal scheduling performs the best and the round-robin has the worst performance in terms of the secrecy outage probability . Last, as the number of users increases, the secrecy outage probabilities of the suboptimal and optimal scheduling schemes decrease significantly.

On the Secrecy Sum-Rate of Internet of Things Networks: Scheduling and Power Control

Inkyu Bang, Seong Ho Chae, Bang Chul Jung

Physical-layer security (PLS) has attracted much attention in wireless communications and has been considered one of the main candidates for enhancing wireless security in future 6G networks. Recent studies in the PLS area have focused on investigating and analyzing the characteristics of secure transmissions in multiuser networks (e.g., the massive number of Internet of Things (IoT) devices in 6G networks). Due to the difficulty of obtaining the exact secrecy capacity region in wireless multiuser networks, several alternative methods are used to characterize the secrecy performance of multiuser networks. For example, we can analyze the secrecy sum-rate scaling in terms of the number of users based on multiuser diversity (MUD). In this paper, we propose an opportunistic user scheduling scheme that achieves optimal MUD gain, combined with a power control mechanism for reducing information leakage to multiple eavesdroppers in wireless networks. The proposed scheme considers multiuser transmissions in one scheduling time slot by adopting orthogonal random beamforming at the receiver to exploit the full degrees-of-freedom gain with an assumption that each user (or IoT device) is equipped with a single antenna, and base station and eavesdroppers have multiple antennas. The main contribution of this paper is to derive the analytic result of the achievable secrecy sum-rate scaling in a high signal-to-noise ratio (SNR) regime. We evaluate the performance of the proposed scheduling scheme with a power control mechanism through simulations with both internal and external eavesdropping scenarios. We further discuss the extensibility of our analysis to various applications such as satellite communications and IoT networks.
