Quantum computers will fundamentally change the way we look at humanity’s most complex problems. They promise new insights, from materials science to medicine and climate research. However, this ...

With growing focus on the existential threat quantum computing poses to some of the most crucial and widely used forms of encryption, cryptography engineer Filippo Valsorda wants to make one thing ...

Two researchers have improved a well-known technique for lattice basis reduction, opening up new avenues for practical experiments in cryptography and mathematics. In our increasingly digital lives, ...

Modern encryption relies on mathematical assumptions that quantum computers may soon render obsolete. This technological shift creates new ...

The original version of this story appeared in Quanta Magazine. In our increasingly digital lives, security depends on cryptography. Send a private message or pay a bill online, and you’re relying on ...

The original version of this story appeared in Quanta Magazine. Hard problems are usually not a welcome sight. But cryptographers love them. That’s because certain hard math problems underpin the ...

The FIDO2 industry standard adopted five years ago provides the most secure known way to log in to websites because it doesn’t rely on passwords and has the most secure form of built-in two-factor ...

NIST treats post-quantum cryptography as a separate challenge, running a different program for developing quantum-resistant standards, and the effort has already yielded its first results. For more ...
