Ars Technica: The cryptopocalypse is nigh! NIST rolls out new encryption
standards to prepare.

In the not-too-distant future—as little as a decade, perhaps, nobody knows
exactly how long—the cryptography protecting your bank transactions, chat
messages, and medical records from prying eyes is going to break spectacularly
with the advent of quantum computing. On Tuesday, a US government agency named
four replacement encryption schemes to head off this cryptopocalypse.
Some of the most widely used public-key encryption systems—including those
using the RSA, Diffie-Hellman, and elliptic curve Diffie-Hellman
algorithms—rely on mathematics to protect sensitive data. These mathematical
problems include (1) factoring a key's large composite number (usually denoted
as N) to derive its two factors (usually denoted as P and Q) and (2) computing
the discrete logarithm that key is based on.
