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 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.

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.

The history of Christianity, therefore, must be of concern to all who are interested in the record of man and particularly to all who seek to understand the contemporary human scene.

There may or may not be a God or gods; the Siblings do not concern themselves with proving or disproving such a thing. By definition, gods are more powerful than men, and thus quite able to fend for themselves without help.

It is a very real concern and my view is that everything changed on September 11th and the procedure, the policies that were in place prior to September 11th no longer should apply.

We have to make philosophy itself an object of philosophical concern.

Common sense tells us that this explosion of media sources should eliminate any concern over a lack of diversity of views in the marketplace and competition.

What has any poet to trust more than the feel of the thing? Theory concerns him only until he picks up his pen, and it begins to concern him again as soon as he lays it down.

The idea of it becomes a little freaky if you're dealing with someone who has trouble differentiating between fantasy and reality, but that's a concern no matter what kind of movie you're dealing with.

As soon as you concern yourself with the 'good' and 'bad' of your fellows, you create an opening in your heart for maliciousness to enter. Testing, competing with, and criticizing others weaken and defeat you.

Given the difficulty of resisting such temptations over the longer run, a proper concern for the welfare of congressional souls may well be the ultimate argument in favor of term limitations.

Environmental concern is now firmly embedded in public life: in education, medicine and law; in journalism, literature and art.

It is your concern when your neighbor's wall is on fire.

Much has been said and continues to be said of what little concern the Turks had for the Acropolis treasures.

We should have been there shoulder to shoulder with our allies. Our concern is the instability of our government as an ally. We are playing again with national and global security matters.

Frankly, I had thought that at the time Roe was decided, there was concern about population growth and particularly growth in populations that we don't want to have too many of.

It is not as though the process of production holds any mystery for me, I know exactly what it involves and I know the predominant concern in shooting one of those things is production values - or as they would say, seeing it all up there on screen.

The success and the failure are not my concern, but His.

My mission is a cosmic mission. My concern is for all of humanity, and not only this present world, but the world hereafter. My mission penetrates the past, present, and future, and encompasses all humanity.

It doesn't much concern me if Tiger plays in the tournament or no.

Above and beyond the question of how to grow the economy there is a legitimate concern about how to grow the quality of our lives.

Our nation's immigration policy has been of top concern in recent years, and for good reason. With between eight and twelve million illegal aliens in the United States, it is obviously a problem out of control.

We need to enact a strong standard that will stop a terrorist or illegal alien from getting a driver's license because border security is a major concern in a post-September 11th world.
