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," ...

"Large bureaucracies, with the power that the computer gives them, become more powerful," said New York Times reporter David Burnham in a 1983 C-Span interview about his book The Rise of the Computer ...

A two-year-old cryptographic breakthrough has proven difficult to put into practice. But new advances show how near-perfect computer security might be surprisingly close at hand. The method was called ...

Mathematicians are often stereotyped as strictly logical, almost robotic, allowing no time for emotions to affect their work. For Daniel Larsen, this has never been true — in fact, it’s been the ...

A new mathematical framework, built on a branch of number theory called adelic analysis, has produced a complete proof of the ...

Apple says testing missed flaws in new encryption designed to protect against future attacks from quantum computers, so it ...

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 ...
