Abstract

In this letter, a joint security and latency analysis of short packet-based low-altitude communications when the eavesdropper is close to the receiver is addressed. To reveal the impacts of the signal-to-noise ratio (SNR) and block-length on latency in communications, we propose a new metric named secure latency (SL) and derive the expressions for the effective secure probability (ESP) and the average SL. To minimize the average SL, different transmission designs are analyzed, in which the optimal solutions of SNR and block-length are provided. Numerical results validate our analysis and reveal the trade-off between reliability and security and the impacts of the block-length, SNR, and packet-generating rate on average SL, of which SNR and the block-length account for main factors. In addition, we find that the performance of SL can be enhanced by allocating less SNR.

基于短分组的低空通信联合安全延迟设计

本文对窃听者靠近接收方时基于短分组的低空通信的联合安全性和延迟进行了分析。为了揭示信噪比（SNR）和块长度对通信延迟的影响，我们提出了一个新的度量——安全延迟（SL），并推导了有效安全概率（ESP）和平均安全延迟的表达式。为了最小化平均安全延迟，我们分析了不同的传输设计，并给出了信噪比和块长度的最优解。数值结果验证了我们的分析，并揭示了可靠性和安全性之间的权衡，以及块长度、信噪比和包生成率对平均SL的影响，其中信噪比和块长度是主要因素。此外，我们发现分配较小的信噪比可以提高SL的性能。

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
