Cryptography Makes a Post-Quantum Leap

On this episode

About this episode

The cryptography that protects our privacy and security online relies on the fact that even the strongest computers will take essentially forever to do certain tasks, like factoring prime numbers and finding discrete logarithms which are important for RSA encryption , Diffie-Hellman key exchanges , and elliptic curve encryption. But what happens when those problems – and the cryptography they underpin – are no longer infeasible for computers to solve? Will our online defenses collapse? Not if Deirdre Connolly can help it. As a cutting-edge thinker in post-quantum cryptography, Connolly is making sure that the next giant leap forward in computing – quantum machines that use principles of…
