Re: [Roll] PLEASE Comment on draft-alexander-roll-mikey-lln-key-mgmt

[Yoshihiro Ohba <[e-mail]>]

Hello,

I think a cross-layer key management approach is important for
resource-constrained devices.  On the other hand, there are similar
approaches proposed in other IETF WG:

http://tools.ietf.org/id/draft-arkko-core-security-arch-00.txt
http://tools.ietf.org/id/draft-garcia-core-security-02.txt
http://tools.ietf.org/id/draft-sarikaya-core-sbootstrapping-02.txt
http://tools.ietf.org/id/draft-ohba-core-eap-based-bootstrapping-00.txt

(and I am a co-author of the last two ones.)

MIKEY-based cross-layer key management (such as described in
draft-alexander) can be an alternative, and similar solutions can be
defined using other key management protocols such as PANA, TLS,
IKEv2, GDOI and maybe HIP.

I am not trying to compare them here, but I just want to point out
that there are multiple approaches in this area.

Regards,
Yoshihiro Ohba
