The Null Device
Cambridge academic
debunks "crypto menace" myth. (NewScientist)
Think what England was like when the government didn't really exist:
anyone with any wealth or property had to design their house to withstand
infantry-strength assault. That's not efficient. National governments and policemen will
survive the electronic revolution because of the efficiencies they create.
If I were to hold a three-hour encrypted conversation
with someone in the MedellĂn drug cartel, it would be a dead giveaway. In routine
monitoring, GCHQ (Britain's signals intelligence service) would pick up the fact that there
was encrypted traffic and would instantly mark down my phone as being suspect. Quite
possibly the police would then send in the burglars to put microphones in all over my house.
In circumstances like this, encryption does not increase your security. It immediately and
rapidly decreases it. You are mad to use encryption if you are a villain.
