US government requesting ideas for quantum-proof cryptography

The US National Institute of Standards and Technology (NIST) has issued “Notice and request for nominations for candidate post-quantum algorithms”. The NIST observes that, once the quantum computers are built and widely available, the entire public-key cryptography of today may be obsolete, and all the encrypted documents may become compromised. While the deadline for submissions of the ideas is set to end of November 2017, NIST acknowledges that, most likely, the work could be widely-tested within next 20 years only, The Register reports.
