Wang Chao and his colleagues at Shanghai University have announced that they have developed a method to break RSA encryption, a cryptography whose security is based on the difficulty of prime ...

Digital security depends on the difficulty of factoring large numbers. A new proof shows why one method for breaking digital encryption won’t work. My recent story for Quanta explained a newly proved ...

Nearly three decades ago, a new method for encrypting digital information transformed online security. Dubbed RSA↓ RSA stands for “Rivest–Shamir–Adleman,” the surnames of its inventors. , it exploited ...

For the last two days my inbox (and LinkedIn messages) has been flooded with questions about headlines claiming that “Chinese researchers broke RSA encryption with a quantum computer, threatening ...

Researchers are closing in on deciphering 1,024-bit RSA encryption, security industry watchers said following an unprecedented numbers-cracking feat by a group of French, German, and Japanese ...

Prime numbers are all the rage these days. I can tell something’s up when random people start asking me about the randomness of primes—without even knowing that I’m a mathematician! In the past couple ...

As computers and math techniques become more powerful and sophisticated, current encryption standards could be made obsolete in as little as five years The strength of the encryption used now to ...
