Chapter 15 Emission Security

Introduction Emissions Security (Emsec) Tempest defenses Stray RF emitted by Electronics Power Analysis Set back Smart Card industry Electro magnetic eavesdropping ATMs Wireless Technologies RF devices

History Crosstalk between lines WWI laid transmission cables on ground, could then easily intercept traffic Used in Britain to detect number of TVs Power Analysis used to detect number of phones 1996 attack on smart cards set the industry back (power analysis)

Emsec attack devices Radio microphone, camera (the x10) Laser Microphones High end devices Tempest devices Countermeasures Nonlinear junction detector Surveillance receivers Physical measures

Other attacks Cordless phones are easy to eavesdrop PBX can be reprogrammed to support surveillance Laptops with microphones can record messages in a room and them to the attacker NSA banned furbys

Passive attacks Take advantage of signals available Power analysis Signals often transmitted out over power lines Red/black separation Smart cards Leakage through RF signals
