We’re not being asked to choose between security and privacy. We’re being asked to choose between less security and more security.
This trade-off isn’t new. In the mid-1990s, cryptographers argued that escrowing encryption keys with central authorities would weaken security. In 2011, cybersecurity researcher Susan Landau published her excellent book Surveillance or Security?, which deftly parsed the details of this trade-off and concluded that security is far more important. Ubiquitous encryption protects us much more from bulk surveillance than from targeted surveillance. For a variety of technical reasons, computer security is extraordinarily weak.
If a sufficiently skilled, funded, and motivated attacker wants in to your computer, they’re in. If they’re not, it’s because you’re not high enough on their priority list to bother with. Widespread encryption forces the listener – whether a foreign government, criminal, or terrorist – to target. And this hurts repressive governments much more than it hurts terrorists and criminals.
