AI总结:

本研究展示两名攻击者通过协调电磁侧信道攻击,重建电子投票机显示选票并关联特定选民,实验验证了穿墙选票重建的可行性,为电子投票安全提供建议。

AI中文摘要:

在这项工作中,我们展示了两个 adversaries(Eve 和 Mallory)如何协调电磁侧信道攻击,以重建电子投票机(EVM)上显示的选票,并将其与特定选民(Alice)关联。假设 Eve 可以进入电子投票室附近的场所(例如洗手间、无人监管的房间),她通过拦截与视频信号相关的非预期电磁辐射来进行选票重建。与此同时,Mallory 观察 Alice 何时投票,并通过互联网将此信息报告给 Eve。为了验证攻击最关键的阶段,我们使用巴西官方电子投票界面进行软件定义无线电实验,并演示了穿墙选票重建。尽管使用的是传统显示器而非官方 EVM,我们的发现为信息取证提供了见解,并为负责电子投票系统的政府当局提供了安全建议。

英文摘要:

In this work, we show how two adversaries (Eve and Mallory) can coordinate an electromagnetic side-channel attack to recon- struct the vote displayed on an e-voting machine (EVM) and link it to a specific voter (Alice). Assuming that Eve has access to a place adjacent to the e-polling room (e.g., restroom, unsupervised room), she performs vote reconstruction by intercepting un- intended electromagnetic emanations associated with the video signal. Meanwhile, Mallory observes when Alice is voting and reports this information to Eve over the Internet. To validate the most critical stage of the attack, we conduct a software-defined radio experiment using the official Brazilian e-voting interface and demonstrate through-wall vote reconstruction. Although conventional monitors are employed rather than official EVMs, our findings provide insights into information forensics and support security recommendations for government authorities responsible for e-voting systems.
