Hi Mohit, the draft contains a lot of information, thank you for that.
I'm just not so sure what to do with it in LWIG. There is some information about a potential security architecture. I would expect to discuss this in ACE, as it's not particularly about implementation. There is some information about crypto libraries for constrained devices. Some of it is about RSA, some of it for older ECC curves. I didn't find anything about P-256 (CoAP's current MTI curve) or the 25519 curves, which are the more likely ones to be used going forward. So I'm wondering a bit what an implementer of IETF IoT protocols can take home specifically here.
