I was reading http://www.schneier.com/blog/archives/2007/05/reading_lcd_dis.html about LCD emissions "Reading LCD Displays at a Distance".
Some one said something about >>>>...The article states that, "the aim is to tune into the radio emissions produced by the cables sending a signal to the monitor..." Because HD over HDMI requires over-the-cable encryption (using secret keys in the graphics and monitor hardware), HDMI is not vulnerable to this attack.<<<< What it is HDMI, is it supported y OpenBSD? another one at http://www.newscientist.com/blog/technology/2007/04/seeing-through-walls.html says: >>>< ...After some research, it was found that the biggest EM leakage source that could be easily decoded was the cable between the keyboard and system. He simply used a passive optical pipe with led's in the keyboard and the keys would act as shutters to interrupt the light. No EM at all. The monitor and monitor cables were all heavily shielded to avoid leakage there....<<<< Anyone knows if OpenBSD encrypts what is going on the cable between the keyboard and system? It seems to me that win anti-keyloggers software does this. Another one says: >>>>The best solution might be already there in Vista. If the video card and the monitor use HDCP for encryption, there will be very little to eavesdrop on. Wow, DRM might be useful one day! (Or am I missing something here?)>>>> What the hell is that Vista videocard and monitor encryption? Is this available in OpenBSD? Thanks for any light on anti-tempest settings for OpenBSD desktops. _______________________________________________ Openbsd-newbies mailing list [email protected] http://mailman.theapt.org/listinfo/openbsd-newbies
