Liaisons referred by this one LS on PQC transition for RFC 6509
Body 
1. Description

Thank you for the inquiry [1] on RFC 6509 [2].  The IETF Security Area
Directors [3] have surveyed the appropriate working groups and the IRTF's CFRG
[4]. While parts of the MIKEY suite of protocols are already quantum resistant
(the symmetric algorithms/modes), RFC 6509 is not.  It is unclear how easy or
possible an update that is secure would be. The IETF and IRTF's CFRG do not
have plans to update this Informational RFC.

2. Upcoming Meetings

IETF 125, 14 - 20 March 2026, Shenzhen, China
IETF 126, 18 - 24 July, Vienna, Austria
