Seeking Quantum Resistant Crypto

Its been suggested that quantum computing will break current cryptographic methods.  So work is underway to find quantum=resistant methods. Not mention of quantum-proof.   NIST has beenholda competition.    Note the mention of dealing wit devices with less computing power, hinting at broader IOT application.

NIST Narrows Field of Post-Quantum Crypto Contenders 
Federal Computer Week   By Susan Miller

The U.S. National Institute of Standards and Technology (NIST) intends to supplement or supplant three public-key cryptosystem standards that are most prone to attacks by large-scale quantum computers now in development: FIPS 186-4, specifying the suite of algorithms for producing digital signatures; and NIST SP 800-56A and NIST SP 800-56B, which relate to establishing keys employed in public-key cryptography. Since 2016, NIST has been conducting a public contest to choose one or more quantum-resistant public-key cryptographic algorithms. In January, it narrowed the field of candidate algorithms from 69 to 26, in preparation for performance assessments across diverse systems. NIST's Dustin Moody said, "We want to look at how these algorithms work not only in big computers and smartphones, but also in devices that have limited processor power." NIST hopes the cryptographic community will help evaluate the algorithms and offer feedback to support or refute the submitters' security claims.  ... "
