A couple of days ago on The Conversation, I set myself up with a task: to defend the usefulness of so-called “useless” maths. Today, that defence continues, with a look at the RSA algorithm. I ...

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 ...

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 ...

A recent research paper makes the claim that the RSA cryptographic algorithm can be broken with a quantum algorithm. Skeptics warn: don’t believe everything you read. Every CISO has encryption ...
