[net.crypt] LISTENING IN - Electronic evesdropping countermeasures

mdr@reed.UUCP (Mike Rutenberg) (12/04/85)

Several postings have asked about aspects of communications security.
There was a very nice article in IEEE's Spectrum (July 1985) which
discussed everything from tapping phone circuits (microwave &
subscriber equipment) to methods IBM uses to protect it's proprietary
information (including voice encryption).  It is a good place to start.
