Zitat des Tages von Whitfield Diffie:
I call up Amazon. It seems to me they do a major thing wrong, right. I mean, they protect me against the loss of a $50 liability I have of something on my credit card, but they do nothing to protect me against somebody who is watching to see what books I'm interested in, what new perversions I've developed.
I certainly enjoy going on stage and lecturing and talking to Congress. That's a personality explanation. And given government proposals, I thought I had a clear view that they were antagonistic to human freedom.
It isn't that secrets are never needed in security. It's that they are never desirable.
One of the things that characterizes good intellectual work is a certain self-importance.
If you have ambition, you might not achieve anything, but without ambition, you are almost certain not to achieve anything.
People constantly face problems they've never seen before, and they have to solve them somehow. So a million people come up with a million solutions that are just a little bit different. If computing is being done by fewer resources, there will be enormous security gains by pushing things into standard practices.
I liked Berkeley tremendously, Berkeley was a very leftist campus. I came to love that city as much as I love Paris or the south of France or New York.
We have experienced an utter explosion in investigative techniques. Walk the streets, look at the cameras! They are now recognising people automatically from photos; we have DNA fingerprinting, infrascan photos that can identify you from the veins in your face.
I understood the importance in principle of public key cryptography but it's all moved much faster than I expected. I did not expect it to be a mainstay of advanced communications technology.
Some people make sharp distinctions sort of between their recreational musings and their professional work. I don't make that distinction very much.
Two people can work on a problem better than one.
I thought cryptography was a technique that did not require your trusting other people-that if you encrypted your files, you would have the control to make the choice as to whether you would surrender your files.
We in science are spoiled by the success of mathematics. Mathematics is the study of problems so simple that they have good solutions.
Lots of people working in cryptography have no deep concern with real application issues. They are trying to discover things clever enough to write papers about.
Cloud computing means you are doing your computing on somebody else's computer. Looking ahead a little, I firmly believe cloud - previously called grid computing - will become very widespread. It's much cheaper than buying your own computing infrastructure, or maybe you don't have the power to do what you want on your own computer.
It's simply unrealistic to depend on secrecy for security in computer software. You may be able to keep the exact workings of the program out of general circulation, but can you prevent the code from being reverse-engineered by serious opponents? Probably not. The secret to strong security: less reliance on secrets.
I think that the people who are trying to shut down WikiLeaks are going to have to accept this as a fact of reality that cryptography allows you to do this kind of thing.
