[$] Disagreements over post-quantum encryption for TLS

The

Internet Engineering Task Force (IETF) is the standards body responsible
for the TLS encryption standard — which your browser is using right now
to allow you to read LWN.net. As part of its work to keep TLS secure, the IETF
has been entertaining

proposals to adopt 'post-quantum' cryptography (that is,
cryptography that is not known to be easily broken by a quantum computer) for TLS
version 1.3. Discussion of the proposal has exposed a large disagreement between
participants who worried about weakened security and others who worried about
weakened marketability.
