The very prospect of the quantum apocalypse has driven various stakeholders to consider what that could be like and how to prepare. For instance, in 2015, the U.S. Natio ...

Building a utility-scale quantum computer that can crack one of the most vital cryptosystems—elliptic curves—doesn’t require nearly the resources anticipated just a year or two ago, two independently ...

By the time Bitcoin and other networks are ready to defend themselves, it may already be too late, according to a new ...

In 1994, Peter Shor, an American mathematician working at Bell Labs, published a paper with a wonky title and earth-shaking implications. In “Polynomial-Time Algorithms for Prime Factorization and ...

Michael Shaulov argued that changing to a post-quantum cryptographic signature scheme is “not a technical challenge” for ...

Building on a landmark algorithm, researchers propose a way to make a smaller and more noise-tolerant quantum factoring circuit for cryptography. The most recent email you sent was likely encrypted ...

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 ...
