definition of term "composite"

[falko-strenzke]

Regarding the sentence in the introduction:

"Here, the term "composite" indicates that the combination of the two components forms a single atomic object.

I don't think that this sentence is saying something useful. Clearly, they are not essentially atomic (as nothing is in the known universe, not even atoms). What is meant here, is that they appear as single cryptogrpaphic schemes on the protocol layer. Accordingly, that is what I would propose to state here.

they appear as single cryptogrpaphic schemes on the protocol layer

I think this was the original statement and we replaced it. The problem I raised was that "protocol layer" is not clear terminology. In internal discussions we distinguish protocol and algorithm layer but in the draft everything is the protocol layer.

Perhaps we can just phrase it slightly differently, for example that they appear as single cryptographic schemes to the rest of the protocol.

[falko-strenzke]

If the word "layer" is the problem, then I propose just to leave it out and say: "they appear as single cryptographic schemes in the protocol".
