NSA Says it “Must Act Now” Against the Quantum Computing Threat

he National Security Agency did a surprising thing last August – it suddenly declared that the algorithms it had spent a decade telling the world were the best way to lock up secret data weren’t safe anymore. The reason? The danger of quantum computers.

The catch is that no one knows how to make quantum-computer-proof encryption. The NSA can only tell companies building new systems to use certain algorithms “believed to be safe from attack by a large quantum computer.” It says it’s working with the National Institute of Standards and Technology on coming up with some new standard algorithms that could survive in a post-quantum era.
