A recent, yet to be proven paper claiming to have found a way to "destroy the RSA cryptosystem" has cryptographers asking what might replace it. What if a big crack appeared overnight in the ...

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 ...

RSA encryption is a major foundation of digital security and is one of the most commonly used forms of encryption, and yet it operates on a brilliantly simple premise: it's easy to multiply two large ...

A new study suggests that breaking RSA encryption with quantum computers may require 20 times fewer resources than previously thought. Although Bitcoin uses elliptic curve cryptography, it remains ...

Classical public-key cryptography derives its security from integer factorisation. Diagram by Venus Kolhi. Quantum computers bring exponential computing power, ultrafast calculations, advanced ...

Hot on the heels of Diffie-Hellman upending the cryptography applecart in 1976 came three more crypto newcomers that further revolutionized the field: Ron Rivest, Adi Shamir, and Leonard Adleman. The ...

Recent headlines have proclaimed that Chinese scientists have hacked "military-grade encryption" using quantum computers, sparking concern and speculation about the future of cybersecurity. The claims ...

The amount of quantum computing power needed to crack a common data encryption technique has been reduced tenfold. This makes the encryption method even more vulnerable to quantum computers, which may ...

There’s little doubt that some of the most important pillars of modern cryptography will tumble spectacularly once quantum computing, now in its infancy, matures sufficiently. Some experts say that ...
