The National Security Agency (NSA), Cybersecurity and Infrastructure Security Agency (CISA), and National Institute of Standards and Technology (NIST) warned that cyber actors could target our nation’s most sensitive information now and leverage future quantum computing technology to break traditional non-quantum-resistant cryptographic algorithms. This could be particularly devastating to sensitive information with long-term secrecy requirements.

The joint Cybersecurity Information Sheet (CSI), “Quantum-Readiness: Migration to Post-Quantum Cryptography,” helps the U.S. Department of Defense, National Security System (NSS) owners, the Defense Industrial Base (DIB), and others proactively protect the confidentiality, integrity, and authenticity of sensitive information.
