Liaisons referred by this one LS on SG17 work item X.ibc-iot: Security framework for using Identity Based Cryptography for IoT services over telecom networks
Body
Thank you for the LS concerning SG17’s work item X.ibc-iot [1].  As you are no
doubt aware, the TLS WG and the IANA TLS Designated Experts worked with the
X.ibc-iot authors, who also are authors of
draft-wang-tls-raw-public-key-with-ibc [2], to register four TLS Signature
Schemes: eccsi_sha256, ibs1_sha256, ibs2_sha256, sm9_ibs_sm3.  These values can
be found in the IANA TLS Signature Scheme registry [3].

We would like to thank those authors for working through the IETF process by 1)
modifying their draft to add ibs1_sha256, ibs2_sha256, and sm9_ibs_sm3 so that
all of the requested values from X.ibc-iot were included, 2) presenting their
draft to the TLS WG at IETF 104, 3) resolving comments from the WG and the
Designated Experts, and 4) for their patience throughout this process.
