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," ...

If you’ve ever picked up a war novel, you know they tend to deal with the exploits of soldiers and sailors, the dirt and danger of the front lines. Not Neal Stephenson’s “Cryptonomicon.” This ...

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 ...

In 1994, the computer scientist Peter Shor discovered that if quantum computers were ever invented, they would decimate much of the infrastructure used to protect information shared online. That ...

Recently, I co-authored and published a math paper that solved a 15-year-old mystery. But, unlike a book or a gadget, the work cannot be copyrighted or bought and sold. In fact, my co-author and I ...

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 ...

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 ...
