The National Security Agency has announced major initiatives to safeguard National Security Systems against the looming threats of quantum computing. The announcement highlights the urgent danger of “Harvest Now, Decrypt Later” attacks, where adversaries store encrypted government data today to unlock it tomorrow. Federal migration mandates require all new commercial National Security Systems to support quantum-resistant algorithms under the CNSA 2.0 framework. The rollout introduces an updated Post-Quantum Cryptography Resources Hub to help agencies and the defense industrial base transition securely. Officials emphasize that moving to quantum-resistant encryption is a complex, critical modernization effort necessary to maintain long-term national security.
