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 ...

Hidden inside a simple color-mixing analogy is one of the most elegant ideas in cryptography, a mathematical trap door that lets two strangers build a shared secret in plain sight. This is the story ...

If you are interested in the real-world applications of numbers, discrete mathematics may be the concentration for you. Because discrete mathematics is the language of computing, it complements the ...

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 ...

Hard problems are usually not a welcome sight. But cryptographers love them. That’s because certain hard math problems underpin the security of modern encryption. Any clever trick for solving them ...
