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 ...

Quantum computers could crack a common data encryption technique once they have a million qubits, or quantum bits. While this is still well beyond the capabilities of existing quantum computers, this ...

Hardware faults are leaking hundreds of supposedly unbreakable encryption keys on to the internet, researchers have found – and spy agencies may be exploiting the loophole to read secret messages. RSA ...
