VoIP Encryption and Privacy in a Surveillance Society 🕵️‍♂️

March 7, 2007 lecture by Phillip Zimmermann for the Stanford University Computer Systems Colloquium (EE 380). Phil talks about how the debate on the use of crypto has shifted since the 1990s, when it was a clash between civil liberties and law enforcement - in the 1990s, the crypto debate was about averting omniscience in governments, but today the encrypted VoIP debate may be about averting omniscience in criminals.
