Words matter. These are the best Whitfield Diffie Quotes, and they’re great for sharing with your friends.
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 thought of computers as very low class. I thought of myself as a pure mathematician and was interested in partial differential equations and topology and things like that.
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.
Cloud computing is a challenge to security, but one that can be overcome.
Some people make sharp distinctions sort of between their recreational musings and their professional work. I don’t make that distinction very much.
I am not convinced that lack of encryption is the primary problem. The problem with the Internet is that it is meant for communications among non-friends.
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.
Without strong encryption, you will be spied on systematically by lots of people.
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.
Intellectual work is essentially a lonely process, and if you can find a way of doing something so that you’re in company without being disturbed, that, for me, is the critical thing. I often get to feel isolated so often if I’m sitting either where there aren’t people or isn’t a view.
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.
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.
I think, and I’ve thought this for a long time, that we live, roughly speaking, in the last generation of human beings.
Two people can work on a problem better than one.
People meet in bars after work all over the world and talk about the great problems of life and death and the world and politics and they don’t take themselves seriously. They can do nothing else except chat about these things in bars after work.
I really believe in the radical viewpoint. And I have always believed that one’s politics and the character of his particular work are inseparable.
The decisions we make about communication security today will determine the kind of society we live in tomorrow.
In a sense, communications networks can be defined entirely by who has cryptographic keys, and I think a lot of networks will work that way in the future.
People are leaving trails everywhere they go; automated web crawlers tell you an awful lot about their social activities. The flow of information in fundamentally unobtrusive ways into social control organisations has risen dramatically.
If you have ambition, you might not achieve anything, but without ambition, you are almost certain not to achieve anything.
One of the things that characterizes good intellectual work is a certain self-importance.
I was, from early on, interested in science. And my parents were very obliging about that. My father used to take me to the museum of natural history, and I knew much more scientific stuff early on. From the time I was 11 or 12, I wanted to be a mathematician.
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.
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.
It isn’t that secrets are never needed in security. It’s that they are never desirable.
