Hello all,

I received offline question about how this work (ACE) relates to DICE, and how it's different.

My answer is the following:

DICE (DTLS In Constrained Environments) WG aims to define a DTLS profile that is suitable for constrained environment, and define how DTLS record layer can be used to transmit multicast messages securely. The objective is to secure message exchanges at the transport layer, and it does not address the authenticated authorization issue. ACE aims to enable authenticated communication between constrained devices, and enable authorization verification to access specific resources. ACE will employ security properties of DTLS whenever possible.

Does this address the question?

Kind Regards
