U.S. CISA Urges Critical Infrastructure to Prepare for Post-Quantum Cryptography

…“In the hands of adversaries, sophisticated quantum computers could threaten U.S. national security if we do not begin to prepare now for the new post-quantum cryptographic standard,” CISA says…

…Symmetric key cryptography, which relies on a single key for data protection, is expected to be less impacted by quantum computers, as long as it starts using longer key sizes, instead of migrating to quantum-resistant algorithms…

…“While quantum computing technology capable of breaking public key encryption algorithms in the current standards does not yet exist, government and critical infrastructure entities—including both public and private organizations—must work together to prepare for a new post-quantum cryptographic standard to defend against future threats,” CISA says…
