RSA Security Inc. pre-empted a number of celebration parties by unexpectedly releasing the widely used RSA public-key encryption algorithm into the public domain ahead of this week’s expiration of 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 ...

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 ...

Adrian Dudek does not work for, consult, own shares in or receive funding from any company or organization that would benefit from this article, and has disclosed no relevant affiliations beyond their ...

As if it wasn't enough that the NSA paid RSA $10 million to adopt an algorithm that wasn't entirely secure, researchers have now demonstrated that they can break even RSA 4096 bit encryption with ...

Cryptography provides the foundation for encryption, privacy and secure communication, and as such it has evolved heavily in the past and it will continue to deal with new threats in the future. You ...

Editor’s note: This article originally published 12-22-13, but was updated 12-23-13 with RSA’s comments. The U.S. National Security Agency (NSA) paid $10 million to vendor RSA in a “secret” deal to ...

RSA is firing back at researchers who claim in a paper that its flagship crypto system is damaged goods. But the report is still difficult to dismiss. My colleague Ellen Messmer wrote about RSA’s ...

A new paper claims that a common digital security system could be tweaked to withstand attacks even from a powerful quantum computer. Math is hard. Indeed, much of the modern infrastructure for secure ...
