As regular Chad’s News readers already know, the current public-key encryption scheme will be useless once we build quantum computers with enough qubits. So scientists have been searching for an encryption method that’s less susceptible to quantum computing algorithms. Turns out that one such scheme was developed in 1978 by CalTech mathematician Robert McEliece. It’s safe from all currently-known quantum computing attacks. McEliece’s system is a bit unwieldy—the keys are very large—but expect to hear more about it unless a better quantum-safe method is found.
