US sets post-quantum cryptography deadlines for federal systems

(DigWatch) US President Donald Trump has signed an executive order setting deadlines for federal agencies to migrate high-priority systems to post-quantum cryptography. Executive Order 14409 says large-scale quantum computers could threaten widely used cryptographic systems and create risks for sensitive government data, critical infrastructure and the digital economy. It also highlights ‘harvest now, decrypt later’ attacks, where adversaries collect encrypted information today and decrypt it once quantum capabilities become available. – Securing the Nation Against Advanced Cryptographic Attacks – The White House
