US tightens path to quantum-proof crypto with 2030–2031 deadlines

The White House issued an executive order to speed up the adoption of quantum-resistant cryptography, requiring high-value assets to switch to PQC key establishment by December 31, 2030 and to PQC digital signatures by December 31, 2031. The move shortens timelines by about 4–5 years and establishes government-wide coordination, new procurement rules for contractors, and guidance on a cryptographic bill of materials, all in response to advancing quantum computing and the risk of future decryption of stored data. The plan relies on collaboration with NIST, DoD, DHS, and other agencies, and marks a shift from earlier 2035–2033 targets for many systems.
