摘要：
短距离可靠安全通信在战术、军事和灾害响应中至关重要，传统通信基础设施往往不可用或易受拦截。当前VHF/UHF电台和软件定义电台虽流行，但体积大且耗电多，不适合作为轻便可穿戴设备使用。本文提供了一种微型LoRa加密通信设备的设计和理论框架，可在1-1.5公里范围内实现可靠通信，且需视距条件。该系统包括语音激活采集模块、数字音频压缩、嵌入式微控制器处理器、AES-128加密及低功耗LoRa传输。通过使用啁啾扩展频谱调制技术，利用LoRa的远距离和低能耗特性，确保了可靠通信、低功耗和低电磁足迹。通过链路预算分析验证了通信范围的实用性。该架构强调基础设施无关性、点对点安全性和可穿戴人体工学。该方案展示了LoRa技术在传统物联网遥测中的潜力，并可进一步扩展至安全战术语音通信平台。
英文摘要：
Short-range reliable and secure communication is a major priority in the tactical, military and disaster response settings where the traditional communication infrastructure is either off-line or prone to interception. Current VHF/UHF radios and software-defined radios are popular but large-sized devices and require lots of power, making them not suitable to be used as lightweight wearable devices with seamless hand-free use. In this paper, the design and theoretical framework of a miniature, LoRa based encrypted intercommunication device that can be used in secure field communication over a range of 1-1.5km and under line-of-sight conditions is provided. The suggested system consists of a voice-activated acquisition block, digital audio compression, an embedded microcontroller processor, and AES-128 encryption followed by a low-power transmission via the LoRa protocol. Through the ability of chirp spread spectrum modulation to utilize the long-range and low-energy properties, the system is guaranteed reliable communications coupled with low power consumption and low electromagnetic footprint. The theoretical analysis of the proposed communication range is justified using a link-budget that justifies the practicability of the communication range in the real propagation conditions. This architecture focuses on infrastructural agnosticism, peer-to-peer security as well as wearable ergonomics. The given scheme shows the possibilities of LoRa technology in the scope of other traditional IoT telemetry, and it can be further extended to include secure tactical voice communication platforms.
