With shared pages, the spy program can ensure that a specic memory line is evicted from the whole cache hierarchy. The spy uses this to monitor access to the memory line." The fact you need to get gnupg to share the pages in question with you does mean that this isn't, by itself, a knockout blow. Still quite the interesting attack. And attacks always improve. Maybe somebody will find a way to do better...
