Checking done, a few nits below but I've asked for IETF last call. Please fix these before IESG evaluation (I don't mind if you do 'em now or later on). Cheers, S. - 4.1.1.2 s/Figure 4 and Figure 4/Figure 4 and Figure 5/ I guess - 6.1 s/has to be know./has to be known./ - 6.1 maybe some quotes would help here, i.e. OLD: We call the above-listed information device credentials NEW: We call the above-listed information "device credentials," - 6.1 s/are often called 'root of trust'/are often called a 'root of trust'/ - 6.1 s/these initial device credential/these initial device credentials/ - 6.1 nicely says "it MUST be ensured that a different key pair" I think that'd be better if you said "different secret key materials" as then that'd also cover the pre-shared key case. (I don't think there are cases where we want to recommend the same secrets be on many devices and those be used with TLS.) - 6.2 s/shorted authentication tag/shorter authentication tag/ - 14: one of the changes doesn't read correctly, I think you're saying the right thing but the surrounding text results in oddness, maybe OLD: Since many IoT devices do not have access to an accurate clock, it is RECOMMENDED to place a sequence of random bytes in the two components of the 'Random' structure when creating a ClientHello or ServerHello message and not to assume a structure when receiving these payloads. NEW: However this structure is being deprecated for privacy reasons so it is RECOMMENDED to place a sequence of random bytes in the two components of the 'Random' structure when creating a ClientHello or ServerHello message and not to assume a structure when receiving these payloads. But I'm not sure if my NEW suggestion there is quite right either. - ID nits whines [1] about a few things, please check those out.
