Having just read about EMRTempest eavesdropping; I find myself wondering whether

  • EMR eavesdropping is defeated by FCC regulations on interference
  • With the advance of technology from CRT to the newer LCD/Plasma monitors, hand-held devices/tablets equipped with a touch-screen and such are as susceptible to EMR eavesdropping as the old CRT monitors.

Thoughts, please?

LCD has been shown to be susceptible to Tempest attacks at least http://www.omninerd.com/articles/TEMPEST_Attack_on_LCD - by listening on the signal that was transmitted in the wire to the monitor ... that might work on a plasma as well (but this might not work for like a TV if there are no cables that can leak information)

  • Any thoughts about tablet/smart-phone screens? Having experienced interference on a CRT TV when an adjacent tablet rings, I would guess they are susceptible too ... – Everyone Apr 27 '12 at 15:03
