Is encrypting my email any good at defeating the NSA survelielance? Id my data protected by standard encryption?

Answer:

Encryption works. Properly implemented strong crypto systems are one of the few things that you can rely on. Unfortunately, endpoint security is so terrifically weak that NSA can frequently find ways around it.

I simply thought I'd point out a statement of mine that first appeared in print in 1997 on page 9 of Web Security & Commerce (1st edition, O'Reilly, 1997, S. Garfinkel & G. Spafford):

Secure web servers are the equivalent of heavy armored cars. The problem is, they are being used to transfer rolls of coins and checks written in crayon by people on park benches to merchants doing business in cardboard boxes from beneath highway bridges. Further, the roads are subject to random detours, anyone with a screwdriver can control the traffic lights, and there are no police.

I originally came up with an abbreviated version of this quote during an invited presentation at SuperComputing 95 (December of 1995) in San Diego. The quote at that time was everything up to the "Further...." and was in reference to using encryption, not secure WWW servers.

A great deal of what people are surprised about now should not be a surprise -- some of us have been lecturing about elements of it for decades. I think Cassandra was a cyber security professor....
