摘要

B5G/6G 网络在部署更多基站方面面临挑战。不过,台湾的四大运营商已经推出了 VoWi-Fi 通话服务,以保持用户的信号质量和覆盖范围。当用户连接到不信任的 Wi-Fi 网络时,这些服务会带来潜在威胁。因此,作者利用商业设备研究了台湾四大电信公司提供的 VoWi-Fi 通话服务的安全性。作者采用地址解析协议攻击方法,开发了两种绕过现有安全措施的验证攻击:一种是丢弃会话启动协议数据包,另一种是丢弃语音呼叫数据包,这两种攻击都能规避当前的安全防御措施。通过实际实验,作者证实了这两种攻击的可行性,并评估了其潜在危害。因此,作者提出了两种防御方法。第一种是供应用程序和设备制造商使用的反攻击算法,用于检测用户通话环境的安全性。第二种是建议电信运营商实施新的检测机制,以保障用户权益。

VoWi-Fi security threats: Address resolution protocol attack and countermeasures

B5G/6G networks are facing challenges in the deployment of additional base stations. However, Taiwan's four major operators have launched VoWi-Fi calling services to maintain signal quality and coverage for customers. These services pose potential threats when users connect to untrusted Wi-Fi networks. Therefore, the authors utilised commercial equipment to study the security of VoWi-Fi calling services offered by Taiwan's four major telecom companies. The authors employed address resolution protocol attack methods to develop two verification attacks that bypass existing security measures: one for dropping session initiation protocol packets and the other for dropping voice call packets, both capable of circumventing current security defences. Through real-world experiments, the authors confirmed their feasibility and assessed their potential harm. Consequently, two defence methods are proposed. The first is an anti-attack algorithm for app and device manufacturers to detect the security of the user's calling environment. The second is a recommendation for telecom operators to implement new detection mechanisms to safeguard user rights.

The cover image is based on the Case Study VoWi-Fi security threats: Address resolution protocol attack and countermeasures by Kuan-Chu Lu et al., https://doi.org/10.1049/ntw2.12113
