The RSA algorithm (Rivest-Shamir-Adleman) is a public key cryptosystem that uses a pair of keys to secure digital communication and transactions over insecure networks, such as the internet. RSA is a ...

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 ...

RSA is dead, long live RSA! At the end of December 2022, Chinese researchers published a paper claiming that they can crack RSA encryption using current-generation quantum computing. For decades, the ...

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 ...

The U.S. National Security Agency (NSA) paid $10 million to vendor RSA in a “secret” deal to incorporate a deliberately flawed encryption algorithm into widely used security software, according to a ...

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 ...

Many people worry that quantum computers will be able to crack certain codes used to send secure messages. The codes in question encrypt data using “trapdoor” mathematical functions that work easily ...

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 ...
