US government could mandate quantum-resistant encryption starting July

In July, the US government is set to specify three encryption algorithms as part of 'post-quantum cryptography' to safeguard against future quantum computer threats. This move comes in response to the looming quantum threat, even though quantum computers capable of such attacks don't exist yet. The National Institute for Standards and Technology (NIST) will establish an international standard for encryption to protect everything from national secrets to online transactions

Companies handling sensitive projects for the US government will be required to adopt these encryption standards, with compliance expected by 2035. The mandate is a proactive measure against potential adversaries adopting a 'harvest now, decrypt later' strategy, emphasizing the importance of securing data against future cyber threats.
