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 ...

The National Security Agency is the largest employer of mathematicians in the US. Maths is a core discipline at the NSA, and mathematicians work on signals intelligence and information security. Why ...

Today, PKC forms the foundation for e-commerce, allowing more than US$1 trillion per day in foreign exchange transactions in North America alone. 10 This technology also allows electronic banking, ...

Newly written code, called the Generalized Knapsack Code, could thwart hackers armed with next generation quantum computers. The encryption codes that safeguard internet data today won't be secure ...

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 ...

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 ...

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 ...
