Whitfield Diffie Quotes

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.
If you are designing cryptosystems, you've got to think about long-term applications. You've got to try to figure out how to build something that is secure against technology in the next century that you cannot even imagine.
If you depend on a secret for your security, what do you do when the secret is discovered? If it is easy to change, like a cryptographic key, you do so. If it's hard to change, like a cryptographic system or an operating system, you're stuck. You will be vulnerable until you invest the time and money to design another system.
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.
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.
It isn't that secrets are never needed in security. It's that they are never desirable.
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.
No right of private conversation was enumerated in the Constitution. I suppose it never occurred to anyone at the time that it could be prevented.
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.
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.
The decisions we make about communication security today will determine the kind of society we live in tomorrow.
The most important impact of technology on communications security is that it draws better and better traffic into vulnerable channels.
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.
Without strong encryption, you will be spied on systematically by lots of people.
