SUMMARY:Electromagnetic eavesdropping on computers - Markus Kuhn (Universi
 ty of Cambridge)

DESCRIPTION:The traditional techniques for remote unauthorized access to p
 rivate and confidential  information -- tapping communication links\, code
  breaking\, impersonation -- become increasingly  infeasible as the use of
  modern cryptographic protection techniques proliferates. Those in the bus
 iness of obtaining information from other people's computers without conse
 nt -- criminals and  spies\, intelligence agency and law enforcement techn
 icians\, private detectives\, market researchers -- are therefore increasi
 ngly looking for alternative eavesdropping techniques.  One class of alter
 natives utilises those unintentional information leaks caused by the physi
 cal/analogue underlying processes in computers and peripherals that can be
  sensed\, amplified and decoded at a distance.\n\nThis talk provides an in
 troduction\, overview and demonstration of electromagnetic and optical  pa
 ssive eavesdropping techniques for personal computers\, focusing in partic
 ular on video display units.  It will present new techniques for eavesdrop
 ping liquid-crystal and cathode-ray tube displays and will  discuss the in
 formation-security threat posed by these\, along with simple new protectiv
 e measures.\n
