Quotes About Cryptography

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 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.

Yardley's The American Black Chamber

Cryptography [without system integrity] is like investing in an armored car to carry money between a customer living in a cardboard box and a person doing business on a park bench.

Cryptography shifts the balance of power from those with a monopoly on violence to those who comprehend mathematics and security design.

Plaintext a might be represented in a long message by all 26 letters. Conversely, any given ciphertext letter might stand for any one of 26 plaintext letters.

The more a cipher deviates from the simple form in which one ciphertext letter invariably replaces the same plaintext letter, the harder it is to break.

Its coding wheels, stepping a space—or two, or three, or four—after every letter or so, did not return to their original positions to re-create the same series of paths, and hence the same sequence of substitutes, until hundreds of thousands of letters had been enciphered.

one of the essential elements of cryptography: a deliberate transformation of the writing.

they employed a device called the "skytale," the earliest apparatus used in crypto-logy

There are two kinds of cryptography in this world: cryptography that will stop your kid sister from reading your files, and cryptography that will stop major governments from reading your files.

Computers had their origin in military cryptography-in a sense, every computer game represents the commandeering of a military code-breaking apparatus for purposes of human expression.

Whatever is decoded dies

In 1973, the only cryptographic technology we could get our hands on was classified.

Somebody will be able to overcome any encryption technique you use!

Recently proposed algorithms that involved hiding an encryption key at the intersection point of a multi-dimensional lattice should prove unbreakable, even for a quantum computer.

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.

Alan invented all sorts of ways of expressing things so that only he and I understood. He used language as a place for us to hide.

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

I chose to deal with the science of cryptography. Cryptography began in mathematics. Codes were developed, even from Caesar's time, based on number theory and mathematical principles. I decided to use those principles and designed a work that is encoded.

With original cryptography, you are just trying to secure one narrow thing - say, communications - and you are trying to secure it from a third party. But you can't secure it from the party you are talking to if they forward your email; it doesn't matter how well your email is encrypted.

The tactic seemed to work, so he stuck to the same theme for the next few days, but there was only so much cryptography he could teach before it started squeezing out everything else.
