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 ...

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 ...

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 ...

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 ...
