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 ...

Beyond advanced mathematics or theoretical computing breakthroughs, PQC is about protecting the systems enterprises already ...

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 ...

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 ...

It’ll still be a while before quantum computers become powerful enough to do anything useful, but it’s increasingly likely that we will see full-scale, error-corrected quantum computers become ...

"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 basic feature of number theory, prime numbers are also a fundamental building block of computer science, from hashtables to cryptography. Everyone knows that a prime number is one that cannot be ...

One afternoon in October 1979, Gilles Brassard was swimming outside a beachfront hotel in San Juan, Puerto Rico, when a stranger swam up to him and changed the course of his career. Without so much as ...

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 ...

Quantum computers are coming. Or, at least, that’s what current predictions say. These machines harness the power of quantum mechanics, the set of rules governing how physics operates at atomic and ...

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," ...
