摘要

3GPP Release 19定义的支持无线接入回传的移动性基站（本文称为MWAB）具有动态部署、精准覆盖、高度集成的特性，支持与低空飞行器一体化部署，在传统地面蜂窝网络和天基卫星网络的基础上，面向低空域层构建机动性、标准化、低成本的通信网络。但MWAB设备在网络边缘移动部署，物理环境开放可达，易遭受攻击劫持和非法使用，安全风险由边缘网络渗透至核心网络，而现有低空智联通信网络架构的安全能力难以阻断安全渗透威胁。本文针对低空智联通信网络架构开展端到端脆弱性、攻击威胁及安全风险分析，提出了以三道安全防线为思路、三级协同安全监测能力为关键技术的端到端安全方案，通过现网和实验室环境协同测试充分验证了安全方案的有效性和可推广性，并提出标准化推进思路。

Abstract

The Mobile Base Station supporting wireless Access Backhaul defined in 3GPP Release 19 (referred to as MWAB in this paper) is an NG-RAN node composed of User Equipment (MWAB - UE) and Base Station Equipment (MWAB - gNB). It features dynamic deployment

precise coverage

and high - level integration. Based on traditional terrestrial cellular networks and satellite-based networks

it supports the construction of a mobile

standardized

and low-cost communication network for the low-altitude domain layer. However

MWAB nodes are deployed at the edge of the network and are exposed to an open physical environment

making them vulnerable to attacks

hijacking

and illegal use. Security risks can penetrate from the edge network to the core network

and the security capabilities of the existing low-altitude communication network architecture are difficult to prevent security threats. This report conducts an E2E vulnerability

attack threats

and security risk analysis of the low-altitude intelligent connected communication network. An E2E security solution is proposed

which takes three security lines of defense as the concept and three-level collaborative security monitoring capabilities as the key technology. The effectiveness and scalability of the security solution are fully validated through coordinated testing in the live network and laboratory environments. Also

ideas for promoting standardization are put forward.
