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.

Some people make sharp distinctions sort of between their recreational musings and their professional work. I don't make that distinction very much.

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 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.

If you have ambition, you might not achieve anything, but without ambition, you are almost certain not to achieve anything.

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.

Two people can work on a problem better than one.

One of the things that characterizes good intellectual work is a certain self-importance.

We in science are spoiled by the success of mathematics. Mathematics is the study of problems so simple that they have good solutions.

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.

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.

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 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.

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.

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.

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.

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.

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'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 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.

The secret to strong security: less reliance on secrets.

Democracy cannot succeed unless those who express their choice are prepared to choose wisely. The real safeguard of democracy, therefore, is education.

Well, after I had the heart attack, it was a very simple choice. What the doctor told me I did and I did it religiously. I ate nothing but lean turkey breast or chicken breast or a piece of fish that was very lean. I mean I stayed away from everything.

From now on it is only through a conscious choice and through a deliberate policy that humanity can survive.

We believe that the European Union is facing a truly historic choice.

If you're a sports fan you realize that when you meet somebody, like a girlfriend, they kind of have to root for your team. They don't have a choice.

We choose what attitudes we have right now. And it's a continuing choice.

To say that an artist sells out means that an artist is making a conscious choice to compromise his music, to to weaken his music for the sake of commercial gain.

We in this Congress have a choice. The American people have a right to exercise a choice on this issue, as to whether our men and women will continue to fight and die in a war based on deception and fantasy, or to start bringing the troops home.

The choice is between which mistake is easier to correct: underdoing it or overdoing it.

A man can't be too careful in the choice of his enemies.

We need to teach the next generation of children from day one that they are responsible for their lives. Mankind's greatest gift, also its greatest curse, is that we have free choice. We can make our choices built from love or from fear.

I don't know whether these people are going to find themselves, but as they live their lives they have no choice but to face up to the image others have of them. They're forced to look at themselves in a mirror, and they often manage to glimpse something of themselves.

You always do what you want to do. This is true with every act. You may say that you had to do something, or that you were forced to, but actually, whatever you do, you do by choice. Only you have the power to choose for yourself.

It will be of little avail to the people that the laws are made by men of their own choice if the laws be so voluminous that they cannot be read, or so incoherent that they cannot be understood.

Soap opera wouldn't be my first choice, but at this point in my life, I would consider a soap. It would allow me to act and still do other things with my life.

Where we have the choice between putting a dollar against those that are going to advance horizontal integration and those that are going to sustain current capability, we'd rather put them against the horizontal integration activity.

Man is made or unmade by himself. By the right choice he ascends. As a being of power, intelligence, and love, and the lord of his own thoughts, he holds the key to every situation.

At only 20 years old I got married. I was still a kid myself, but in those times, if you got someone pregnant, you had no choice but to get married. So I left school and the only thing I could do was sing.

And before our current legislature adjourns, we intend to become the first state of full and true choice by saying to every low and middle-income Hoosier family, if you think a non-government school is the right one for your child, you're as entitled to that option as any wealthy family; here's a voucher, go sign up.

It was never really my choice to be an action heroine.

This war of choice in Iraq is undermining the very fabric of American society.
