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

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.

Focusing your life solely on making a buck shows a certain poverty of ambition. It asks too little of yourself. Because it's only when you hitch your wagon to something larger than yourself that you realize your true potential.

Don't let ambition get so far ahead that it loses sight of the job at hand.

The truth is really an ambition which is beyond us.

Ambition can be a disease, and it feeds on itself.

My craziest ambition is to take John Madden's job and salary.

There has to be this pioneer, the individual who has the courage, the ambition to overcome the obstacles that always develop when one tries to do something worthwhile, especially when it is new and different.

To be happy at home is the ultimate result of all ambition, the end to which every enterprise and labor tends, and of which every desire prompts the prosecution.

I'm just a ballplayer with one ambition, and that is to give all I've got to help my ball club win. I've never played any other way.

Ambition has one heel nailed in well, though she stretch her fingers to touch the heavens.

People in the U.K. cannot understand whether Blair has lost his mind or whether his ambition to be the second-most-powerful man in the world made him lose his mind.

One thing all stage mothers share is an overpowering ambition for their daughters.

Moderation has been called a virtue to limit the ambition of great men, and to console undistinguished people for their want of fortune and their lack of merit.

Me only have one ambition, y'know. I only have one thing I really like to see happen. I like to see mankind live together - black, white, Chinese, everyone - that's all.

You want the book to be special, and they are not always going to be special, but at least you want that to be the ambition. So the only way that happens is if you are not pressing to write a book.

The average Hollywood film star's ambition is to be admired by an American, courted by an Italian, married to an Englishman and have a French boyfriend.

I should have been smart enough to stay happy. But my ambition ruled my life.

Great ambition, the desire of real superiority, of leading and directing, seems to be altogether peculiar to man, and speech is the great instrument of ambition.

God like Us suffers the ambition to make a destiny more extraordinary than was conceived for Him, yes God is like Me, only more so.

I used to think I had ambition... but now I'm not so sure. It may have been only discontent. They're easily confused.

A young man without ambition is an old man waiting to be.

The preserve of ambition and folly in pursuit of illusion, or delusion.
