关于“热通信”的讨论引发对“空气隔离环境”定义的质疑

Gary Marcus 和 Romeo Lupascu 在讨论一个有趣但可能被过度解读的网络安全概念，值得看看他们的不同看法。
Romeo Lupascu 指出，在“空气隔离环境”的定义中，应排除所有形式的通信，包括热通信。他认为，只要设计得当，即使几米距离也能阻止热通信。他还质疑了 Noam 想要表达的观点，认为这毫无意义。

Spoilsport! How are we gonna panic about heat-based communications between air-gapped computers if you guys keeping bringing reality into it? Romeo Lupascu @RomeoLupascu But this isn't about what's possible. An airgapped environment by definition isn't just two computers that do not have any electrical connectivity but they have NO connectivity at all, regardless of what method you'd imagine aside electric. That means you design and test the "airgap" so that NOTHING can be exchanged in any way. Heat? You can simply put them few meters apart an give no heat sensors to the systems and they can't communicate. In the same line of thinking EM radiation from the processors and current consumption from the power sources could be used to transfer state but you design the "airgap" so that NOTHIG can cross. I mean really are we joking here? And I'm not sure what's the point Noam is trying to make. Really it makes zero sense. 🔗 View Quoted Tweet 💬 0 🔄 1 ❤️ 14 👀 2456 📊 1 ⚡
