Congress Urged to Accelerate Preparation for Quantum Threats to Encryption

Summary

The article warns that future quantum computers could break current encryption and that stolen data may be decrypted later. It urges Congress to coordinate post-quantum cryptography upgrades across government and support protections for critical sectors.

Key points

• A sufficiently powerful quantum computer could break widely used encryption, putting sensitive communications and data at risk.
• The article cites research suggesting fewer resources may be needed to break some encryption than previously estimated, and notes Google's 2029 post-quantum transition target.
• The NSA has selected quantum-resistant algorithms for National Security Systems; a White House order sets federal transition deadlines of 2030 for key establishment and 2031 for digital signatures.
• In “harvest now, decrypt later” attacks, adversaries steal encrypted data today for possible decryption once quantum capabilities advance.
• The author urges assessments of exposure across intelligence, military, state and local government, and critical infrastructure systems.
• The article calls for Congress to fund and coordinate upgrades, including systems designed to adopt new encryption without wholesale replacement.
