Hi all,

During the ACE conference call we had a few new participants, namely Stevie, Piotr and Marius, from the lighting consortium Fairhair attending. Great to see new participants "on-board".

Stevie explained that he needs a document that contains a solution using asymmetric and symmetric cryptography, that they intend to use the asymmetric solution whenever there is no low latency requirement (and for unicast communication), and only use the symmetric key approach when the low latency requirements demand it.

Is this a correct summary?

Ciao
Hannes

PS: Stevie also mentioned that he likes draft-tiloca-ace-oscoap-joining-00.txt but not draft-somaraju-ace-multicast<https://tools.ietf.org/html/draft-somaraju-ace-multicast>. This was rather surprising since draft-somaraju-ace-multicast<https://tools.ietf.org/html/draft-somaraju-ace-multicast>was written by the lighting community (in the OpenAIS project) specifically addressing the low latency requirements of that community. Stevie, could you explain?
