In mathematics, proofs can be written down and shared. In cryptography, when people are trying to avoid revealing their ...

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 ...

Introduction to ciphers and substitution. Alice and Bob and Carl and Julius: terminology and Caesar Cipher ; The key to the matter: generalizing the Caesar Cipher ; Multiplicative ciphers ; Affine ...

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 ...

"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 ...

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 ...

Top artificial intelligence systems now ace many textbook-style math questions, yet they still fall apart on genuinely new ...

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 ...

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 ...
