Cryptographic Quotes & Sayings

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. — Whitfield Diffie

Humans are incapable of securely storing high-quality cryptographic keys, and they have unacceptable speed and accuracy when performing cryptographic operations. (They are also large, expensive to maintain, difficult to manage, and they pollute the environment. It is astonishing that these devices continue to be manufactured and deployed. But they are sufficiently pervasive that we must design our protocols around their limitations.) — Charlie Kaufman

There are almost 200 currencies of the world, but there's only one international currency. There are almost 200 currencies controlled by central banks and governments, but there is only one mathematical currency today, and that is bitcoin. We are going to build more of them. Cryptographic currencies are going to be a mainstay of our financial future. They are going to be a part of the future of this planet because they have been invented. It's as simple as that. You cannot un-invent this technology. You cannot turn this omelette back into eggs. — Andreas M. Antonopoulos

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. — Whitfield Diffie

General Joseph O. Mauborgne, who became Chief Signal Officer in October, 1937. Mauborgne had long been interested in cryptology. In 1914, as a young first lieutenant, he achieved the first recorded solution of a cipher known as the Playfair, then used by the British as their field cipher. He described his technique in a 19-page pamphlet that was the first publication on cryptology issued by the United States government. In World War I, he put together several cryptographic elements to create the only theoretically unbreakable cipher, and promoted the first automatic cipher machine, with which the unbreakable cipher was associated. He was among the first to send and receive radio messages in airplanes. As — David Kahn

To a degree which is difficult to determine, the esoteric impulse in twentieth-century music, literature and the arts reflects calculation. It looks to the flattery of academic and hermeneutic notice. Reciprocally, the academy turns towards that which appears to require its exegetic, cryptographic skills. — George Steiner

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

first ever military cryptographic device, the Spartan scytale, dating back to the fifth century B.C. The scytale is a wooden staff around which a strip of leather or parchment is wound, — Simon Singh

A specter is haunting the modern world, the specter of crypto anarchy. Computer technology is on the verge of providing the ability for individuals and groups to communicate and interact with each other in a
totally anonymous manner. Two persons may exchange messages, conduct business, and negotiate electronic contracts without ever knowing the true name, or legal identity, of the other. Interactions over networks will be untraceable, via extensive rerouting of encrypted packets and tamper-proof boxes which implement cryptographic protocols with nearly perfect assurance against any tampering. Reputations will be of central importance, far more important in dealings than even the credit ratings of today. These developments will alter completely the nature of government regulation, the ability to tax and control economic interactions, the ability to keep information secret, and will even alter the nature of trust and reputation. — Peter Ludlow

Bitcoin is a remarkable cryptographic achievement and the ability to create something which is not duplicable in the digital world has enormous value — Eric Schmidt
