Trump Orders Federal Systems to Shift to Post-Quantum Cryptography by 2031

On June 22, President Trump signed an executive order requiring U.S. federal agencies to accelerate migration to post-quantum cryptography, with high-impact systems and high-value assets required to adopt quantum-resistant digital signatures by December 31, 2031. The measure, titled Securing the Nation Against Advanced Cryptographic Attacks, also sets a December 31, 2030 deadline for agencies to support quantum-resistant key establishment.

The order is intended to protect government networks against future attacks from quantum computers that could potentially break widely used encryption such as RSA and elliptic-curve algorithms. The White House framed the action as part of a national-security strategy to maintain U.S. leadership in quantum technology while safeguarding sensitive government data.
