Neal Koblitz is a mathematician who, starting in the 1980s, became fascinated by mathematical questions in cryptography. In his article "The Uneasy Relationship Between Mathematics and Cryptography," ...

Cryptography is just about as old as written communication itself, and mathematics has long supplied methods for the cryptographic toolbox. Starting in the 1970s, increasingly sophisticated ...

It all begins with mathematics really - the one true scientific language, so they say. Cryptography has been around as early as 4000 years ago, doing what it still does today - ensuring that secrets ...

Digital security depends on the difficulty of factoring large numbers. A new proof shows why one method for breaking digital encryption won’t work. My recent story for Quanta explained a newly proved ...

Stumped? That’s because it’s encrypted. Well, sorta. The message, if you were curious, reads: “Encryption Matters,” and it’s part of a project by Mozilla — alongside TODO, an Italian creative agency — ...

Riot Blockchain's CEO John O'Rourke explains how the blockchain encryption mining network works. Blockchain encryption prevents sensitive information from getting into the wrong hands, and being ...
