More Details on the NSA Switching to Quantum-Resistant Cryptography
The NSA is publicly moving away from cryptographic algorithms vulnerable to cryptanalysis using a quantum computer. It just published a FAQ about the process:
Q: Is there a quantum resistant public-key algorithm that commercial vendors should adopt?
A: While a number of interesting quantum resistant public key algorithms have been proposed external to NSA, nothing has been standardized by NIST, and NSA is not specifying any commercial quantum resistant standards at this time. NSA expects that NIST will play a leading role in the effort to develop a widely accepted, standardized set of quantum resistant algorithms. Once these algorithms have been standardized, NSA will require vendors selling to NSS operators to provide FIPS validated implementations in their products. Given the level of interest in the cryptographic community, we hope that there will be quantum resistant algorithms widely available in the next decade. NSA does not recommend implementing or using non-standard algorithms, and the field of quantum resistant cryptography is no exception.

Q: When will quantum resistant cryptography be available?
A: For systems that will use unclassified cryptographic algorithms it is vital that NSA use cryptography that is widely accepted and widely available as part of standard commercial offerings vetted through NIST’s cryptographic standards development process. NSA will continue to support NIST in the standardization process and will also encourage work in the vendor and larger standards communities to help produce standards with broad support for deployment in NSS. NSA believes that NIST can lead a robust and transparent process for the standardization of publicly developed and vetted algorithms, and we encourage this process to begin soon. NSA believes that the external cryptographic community can develop quantum resistant algorithms and reach broad agreement for standardization within a few years.
Lots of other interesting stuff in the Q&A.
