In theory, quantum physics can bypass the hard mathematical problems at the root of modern encryption. A new proof shows how.

Modern encryption algorithms hold trueo these two main concepts but are vastly more complex. An encryption system is only as good as the number of possible keys to decrypt it.

But in a study published in the journal Chinese Journal of Computers in May, researchers found that D-Wave Advantage — a ...

Widely used encryption algorithms like RSA and elliptic-curve cryptography (ECC) will be pointless. Depending on who is running the quantum computers, they will turn from superhero to supervillain.

Encryption is an important part of keeping our digital lives private. For the most part, it works well. However, new generations of quantum computers could threaten to decode the algorithms that ...

Modern encryption algorithms exploit the fact that we can easily take two large primes and multiply them together to get a new, super-large number, but that no computer yet created can take that ...

Post-quantum cryptography algorithms use those mathematical operations to protect user data. One such algorithm, Kyber, forms the basis of Apple’s new PQ3 protocol for iMessage.

How long it will take to replace modern cryptography with the post-quantum alternative is anybody’s guess – and there is certain to be an interval of several years where the world has no ...
