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," ...

Quantum computing is widely believed to be a revolutionary new technology. In fact, it is a double-edged sword. If efficient quantum computers can be manufactured in near future, many of the current ...

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 ...

A simple geometric idea has been used to power advances in information theory, cryptography and even blockchain technology. But while the work has generated a lot of excitement among pure ...

For thousands of years, if you wanted to send a secret message, there was basically one way to do it. You’d scramble the message using a special rule, known only to you and your intended audience.

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 ...
